The most popular of these applications was &lt;a class="wikilink" href="http://swik.net/del.icio.us"&gt;del.icio.us&lt;/a&gt;, but it seems to have been caught by &lt;a class="wikilink" href="http://swik.net/digg"&gt;digg&lt;/a&gt;, at least in the &lt;a class="wikilink" href="http://swik.net/Alexa"&gt;Alexa&lt;/a&gt; rankings.&lt;/p&gt;

            <title>Is this the picture of a dying service?</title>
            <link>http://swik.net/User:alex/Alex+Bosworth+-+The+Races/Is+this+the+picture+of+a+dying+service%3F/ilup</link>
            <description>&lt;p&gt;&lt;img src=&quot;http://traffic.alexa.com/graph?w=379&amp;#38;h=216&amp;#38;r=1y&amp;#38;z=&amp;#38;y=r&amp;#38;u=del.icio.us/url/07ac7c8357b1392b0f161477f73829e2&amp;#38;u=&quot; alt/&gt;&lt;/p&gt;


	&lt;p&gt;&lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/del.icio.us&quot;&gt;del.icio.us&lt;/a&gt; appears to be doing fine to me :/&lt;/p&gt;


	&lt;p&gt;I don&amp;#8217;t know what Michael Arrington is smoking when he says quote &lt;a href=&quot;http://www.techcrunch.com/2006/08/04/dazzle-us-again-delicious/&quot;&gt;they&amp;#8217;ve tanked completely&lt;/a&gt;&lt;/p&gt;


	&lt;p&gt;By my internal counters, del.icio.us has well over 300k users who &lt;em&gt;actively post bookmarks&lt;/em&gt;. This is different from &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/Digg&quot;&gt;Digg&lt;/a&gt; or really any of the social sites out there besides the picture and myspace sites &amp;#8211; these are people who are actively contributing to the del.icio.us resource with quality stuff.&lt;/p&gt;


	&lt;p&gt;Digg is pretty ephemeral by comparison, with Diggs occupying a perhaps similar volume of traffic thanks to the easy button, but the tagging and focus on new content means that Digg traffic lives and dies quickly, which may account for why Digg has eclipsed del.icio.us in traffic.&lt;/p&gt;


	&lt;p&gt;However look at the contributor numbers, people have recently claimed that Digg only has a thousand or far fewer active bookmarkers, and my internal numbers from my feeds back that up. &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/LiveMarks&quot;&gt;LiveMarks&lt;/a&gt; has scrolled 60k digg bookmarks, and 4 million unique del.icio.us links over the past year or so.&lt;/p&gt;


	&lt;p&gt;What really seems to have improved at del.icio.us since Yahoo bought them is something that Michael Arrington likely would have a hard time selling as copy: their performance has improved drastically from a near cataclysm of broken pages, timeouts and database failures that were striking del.icio.us shortly before they were sold.&lt;/p&gt;


	&lt;p&gt;The feature improvements have indeed been scarse and the design is still unfortunate, but it&amp;#8217;s still the best public bookmarking service out there by far (of course the new &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/boz&quot;&gt;boz&lt;/a&gt; is the first and best and only truly private bookmarking service :P)&lt;/p&gt;


	&lt;p&gt;Sometimes features and visible improvements take a long time to brew, such as before &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/Flickr&quot;&gt;Flickr&lt;/a&gt; released their Gamma update. There is a ton of work that needs to be done on del.icio.us, but I wouldn&amp;#8217;t count Yahoo as having killed the goose yet.&lt;/p&gt;


	&lt;p&gt;PS: The comscore high Arrington refers to is likely bumped artificially high by press regarding the Yahoo aquisition, not droves of users suddenly signing up and using the service.&lt;/p&gt;

            <title>Social Bookmarking flat this year?</title>
            <link>http://swik.net/User:alex/Alex+Bosworth+-+The+Races/Social+Bookmarking+flat+this+year%3F/cnin</link>
            <description>&lt;p&gt;Looking at the graphs for &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/del.icio.us&quot;&gt;del.icio.us&lt;/a&gt; and its biggest followers, as I&amp;#8217;ve just posted below, it&amp;#8217;s interesting to note that growth for this year is fairly static.&lt;/p&gt;


	&lt;p&gt;&lt;img src=&quot;http://sandbox.sourcelabs.com/alexaimages/20060317socialbookmarking.jpg&quot; alt/&gt;&lt;/p&gt;


	&lt;p&gt;I would have thought that &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/Yahoo&quot;&gt;Yahoo&lt;/a&gt; would be providing more support for del.icio.us, wasn&amp;#8217;t one of the big reasons to go to a big web company to help take social bookmarking to the mainstream?&lt;/p&gt;


	&lt;p&gt;&lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/Digg&quot;&gt;Digg&lt;/a&gt; however is still growing, thanks possibly in part to &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/Kevin-Rose&quot;&gt;Kevin Rose&lt;/a&gt;&amp;#8217;s rush to get features out the door like their much improved comment system, and possibly part of growing to fill the unrealized potential size of tech enthusiast market, digg continues to be first with tech news over everyone else, &lt;a href=&quot;http://diggvsdot.com/&quot;&gt;more now than ever&lt;/a&gt;.&lt;/p&gt;


	&lt;p&gt;The next stage of the &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/social-bookmarking&quot;&gt;social bookmarking&lt;/a&gt; game has got to be making services that deliver more value to the mainstream web user and refinining the anti-spam and social heuristics. (&lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/LiveMarks&quot;&gt;LiveMarks&lt;/a&gt; unfortunately saw a lot of spam today through &lt;a href=&quot;[sexkitten&quot;&gt;del.icio.us user sexkitten&lt;/a&gt;], who posted seven and a half thousand spam bookmarks in the space of ten hours.&lt;/p&gt;


	&lt;p&gt;I have to note however that &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/Alexa&quot;&gt;Alexa&lt;/a&gt; has been most unkind to SWiK lately, completely unjustifiably, we&amp;#8217;ve just had our best week ever according to our internal stats but Alexa shows us down, which is kind of irritating.&lt;/p&gt;


	&lt;p&gt;Our user base isn&amp;#8217;t well tuned for Alexa, having a third of the users not running Windows and fewer than a third running IE, but it&amp;#8217;s still annoying to see our graph go down when we are actually attracting quite a large audience.&lt;/p&gt;

            <description>&lt;p&gt;&lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/Social-Bookmarking&quot;&gt;Social Bookmarking&lt;/a&gt; &amp;#8211; It&amp;#8217;s not just putting periods in awkward places.&lt;/p&gt;


	&lt;p&gt;Social Bookmarking Services were created by &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/Joshua-Schachter&quot;&gt;Joshua Schachter&lt;/a&gt;.&lt;/p&gt;


	&lt;p&gt;&lt;img src=&quot;http://sandbox.sourcelabs.com/alexaimages/20060311sb3.png&quot; alt/&gt;&lt;/p&gt;


	&lt;h2&gt;They evolved.&lt;/h2&gt;


	&lt;p&gt;&lt;img src=&quot;http://sandbox.sourcelabs.com/alexaimages/20060311sb1.png&quot; alt/&gt;&lt;/p&gt;


	&lt;h2&gt;They rebelled.&lt;/h2&gt;


	&lt;p&gt;&lt;img src=&quot;http://sandbox.sourcelabs.com/alexaimages/20060311sb2.png&quot; alt/&gt;&lt;/p&gt;


	&lt;h2&gt;There are &lt;strong&gt;many&lt;/strong&gt; copies.&lt;/h2&gt;


	&lt;h2&gt;And they have a plan&amp;#8230; (sell ads)&lt;/h2&gt;


	&lt;p&gt;&lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/del.icio.us&quot;&gt;del.icio.us&lt;/a&gt; is still the king though, no one even comes close (unless you count &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/digg&quot;&gt;digg&lt;/a&gt;, which is then the &lt;a href=&quot;http://www.alexaholic.com/digg.com+del.icio.us&quot;&gt;#1 social bookmarking site&lt;/a&gt;).&lt;/p&gt;

            <title>Alexadex</title>
            <link>http://swik.net/User:alex/Alex+Bosworth+-+The+Races/Alexadex/byzu</link>
            <description>&lt;p&gt;I saw on the &lt;a href=&quot;http://awis.blogspot.com/&quot;&gt;Alexa blog&lt;/a&gt; a pointer to this really interesting site where sites are bought and sold on their alexa rating, it&amp;#8217;s called &lt;a href=&quot;http://www.alexadex.com/ad/&quot;&gt;Alexadex&lt;/a&gt;.&lt;/p&gt;


	&lt;p&gt;I really like the idea, and I&amp;#8217;ve thought about doing the same thing for &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/social-bookmarking&quot;&gt;social bookmarking&lt;/a&gt; activity. What I like about it is that markets have a really good predictive ability, and I think it would be interesting to see if a social bookmarking market could outperform news/blog sites in finding new and interesting stuff.&lt;/p&gt;


	&lt;p&gt;Of course on the other hand, it&amp;#8217;s possible that blogs make the news, not the other way around. It may be impossible to predict what will be popular ahead of time because what is popular depends purely on the whims of whatever the boing boing editor decides to put on their blog. In any case it would be interesting to find out.&lt;/p&gt;


	&lt;p&gt;Unfortunately what&amp;#8217;s missing from Alexadex is the ability to get a good sense of what sites are up and comers, and I get a feeling that the share prices are all very volatile. It would be interesting though if Alexadex published an &lt;span class=&quot;caps&quot;&gt;API&lt;/span&gt; in turn.&lt;/p&gt;

            <title>Social Bookmarking Vs Spam</title>
            <link>http://swik.net/User:alex/Alex+Bosworth%27s+Weblog/Social+Bookmarking+Vs+Spam/busk</link>
            <description>&lt;p&gt;Social bookmarking is currently in a high growth pattern. I notice it all the time running &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/LiveMarks&quot;&gt;LiveMarks&lt;/a&gt;, the rate of &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/social-bookmarking&quot;&gt;social bookmarking&lt;/a&gt; is increasing every single day.&lt;/p&gt;


	&lt;p&gt;The more people flock to something, the bigger target it is for abuse. The more people turn to &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/del.icio.us&quot;&gt;del.icio.us&lt;/a&gt; to find useful bookmarks, or &lt;a href=&quot;http://digg.com&quot;&gt;digg.com&lt;/a&gt; to read the latest news, the more tempting targets those services become for spammers and vandals.&lt;/p&gt;


	&lt;p&gt;As &lt;a class=&quot;wikilink&quot; href=&quot;http://swik.net/Clay-Shirky&quot;&gt;Clay Shirky&lt;/a&gt; has noted, &lt;a href=&quot;http://www.corante.com/many/archives/2005/02/01/tags_run_amok.php&quot;&gt;&amp;#8220;Social software is stuff that gets spammed.&amp;#8221;&lt;/a&gt; Perhaps as an addendum to that aphorism it should be noted that successful social services are those that can resist spam successfully.&lt;/p&gt;


	&lt;p&gt;The spamming foes of social software are just starting to take shape. Witness a new service called &amp;#8216;&lt;a href=&quot;http://www.tagexplosion.com/&quot;&gt;TagExplosion&lt;/a&gt;&amp;#8217;, TagExplosion describes itself: &lt;blockquote&gt;&amp;#8220;[TagExplosion] helps get your program, blog, advertisement or website on the several &amp;#8220;Social Bookmarking&amp;#8221; sites so you can get on 100,000&amp;#8217;s of computers, worldwide. This will help drive more traffic to your website by utilizing the &amp;#8220;word-of-mouth&amp;#8221; aspect of Social Bookmarking.&lt;/blockquote&gt;&lt;/p&gt;


	&lt;p&gt;Services like these are bound to multiply and exploit every weakness in social bookmarking&amp;#8217;s defenses against spam and general social filters such as Digg&amp;#8217;s front-page promotion mechanism or del.icio.us&amp;#8217;s popularity or aggregation filters.&lt;/p&gt;


	&lt;p&gt;At the moment, the defenses of the social bookmarking sites are fairly weak. Currently del.icio.us has certain filters that destroy obvious spammers, prevent excessive tagging from aggregating onto every tag page, and prune the front page&amp;#8217;s new bookmarks list. But del.icio.us&amp;#8217; only solid defense against automated attack is their signup captcha. As we&amp;#8217;ve seen with &lt;a href=&quot;http://www.blogmaverick.com/entry/1234000717063627/&quot;&gt;BlogSpot&lt;/a&gt;, a signup captcha is only worth what it costs a spammer to pay an Indian or Filipino company to fill in.&lt;/p&gt;


	&lt;p&gt;&lt;a href=&quot;http://del.icio.us&quot;&gt;del.icio.us&lt;/a&gt; may soon have to contend with spammers that post automatically or through peer to peer schemes such as TagExplosion or hide their spam like &lt;a href=&quot;http://en.wikipedia.org/wiki/Steganography&quot;&gt;steganographers&lt;/a&gt;, continuously studying filters to evade and manipulate them.&lt;/p&gt;


	&lt;p&gt;Digg has similar problems, and is currently using similar techniques with similar vulnerabilities. As Digg is a more socially oriented site, it also uses more socially oriented solutions to fight off the spam problem. Users are encouraged not to post duplicate stories by having to first wade through other users&amp;#8217; submissions, and once posted other users quickly respond and post complaintative comments against problematic links. Users of Digg also help fend off spam by reporting what is wrong to the administrators and to the other users watching the live queue.&lt;/p&gt;


	&lt;p&gt;As frequent Digg users are well aware, Digg has had a tough battle in the recent times fighting vandalism. So far however, only a tiny minority vandalize the site, spammers are still thankfully somewhat in the dark as to how they might abuse the system.&lt;/p&gt;


	&lt;p&gt;This is all very reminiscent of the rise of search engines, Compare a search on &lt;a href=&quot;http://www.altavista.com/web/results?itag=ody&amp;#38;q=viagra&amp;#38;kgs=1&amp;#38;kls=0&quot;&gt;Altavista for viagra&lt;/a&gt; to &lt;a href=&quot;http://www.google.com/search?q=viagra&quot;&gt;the same search on Google&lt;/a&gt;. Search engines that failed, failed in large part because spammers eventually reverse engineered the algorithms they used to determine relevance and simply rearranged their pages to suit those algorithms. The top result for viagra: &amp;#8216;t-e-x-a-s-poker.com&amp;#8217; on altavista is the end result of the eventual failure of the first generation algorithms.&lt;/p&gt;


	&lt;p&gt;It&amp;#8217;s likely that to survive and remain useful, social services will have to follow in this mold and emulate Google by switching their filters to factors that are more expensive and more complicated to engineer, such as third party references, longevity, references from known trusted sources, and patterns of human created content. Or they may be forced to become less social, such as with Wikipedia&amp;#8217;s &lt;a href=&quot;http://en.wikipedia.org/wiki/Wikipedia:Semi-protection_policy&quot;&gt;recent&lt;/a&gt; &lt;a href=&quot;http://www.guardian.co.uk/international/story/0,3604,1661693,00.html?gurss&quot;&gt;policies&lt;/a&gt;. Even then, it&amp;#8217;s certain to be an ongoing battle.&lt;/p&gt;
