How many social bookmarking sites are on a slow road to obscurity? Which is best to use?
Web research science tells us that web content has a “long tail”
distribution with an extremely high number of content variations.
Social bookmarking content providers follow this pattern – there are over 50 of them, and none have more than 5% of the total. However, there is a cluster of the strongest – Digg, Del.iciou.us, Reddit, MyWeb (yahoo), Netscape, Google, and Technorati.
Though the value of a network is theoretically supposed to increase exponentially based on the number of nodes, isn’t there a point of negative feedback when the complexity becomes too great? Too many choices can have a negative utility? As Charlene Li has complained, there is no “services architecture” for web 2.0 that provides seamless integration of personal information (social graphs) such as bookmarks. It is a challenge to publishers trying to accomodate user audiences and their numerous social bookmarking options.
I think of bookmarking segmented into three categories, even though there is blurring of the boundaries by some of the sites: general purpose (google bookmarks), blog / comment (bloglines, google blog search, co.mments), and news (digg, reddit).
The nifty Compete.com site shows Digg, Technorati, del.icio.us, and Reddit leading. Insert your own choices on the site and create your own chart.
News-markers Digg / Reddit are growing extremely fast – Digg hits tripled from last year. Netscape and and Google offer bookmarking, but Yahoo is the social bookmarking leader overall after acquiring del.icio.us and launching the myweb.yahoo.com bookmarking this year. Compete’s site is unable to report on subdomains, so myweb.yahoo.com and bookmarks.google.com were omitted from the chart, but I included them in the “read more” segment of this post which also includes the following:

Stumbleupon, Buddymarks, Diigo, Blinklist, Feedmelinks, Newsvine, Magnolia, Wink,
