Web 2.0 Social Tagging Sites, Part 1: Alexa Rankings

Here are the rankings for 42 Web 2.0 social tagging sites, according to Alexa. Although Alexa is notorious for its lack of precision, as documented by GigaOM, SEO Book, BloggingStocks and others, it's still useful as a rough guide to website popularity. A site ranked at 20,000 may not really be more popular than the site at spot 25,000, but it certainly gets more traffic than a site ranked at 200,000. As pointed out at PaulStamatiou.com, "While you shouldn’t quote Alexa rankings as ultimate truth, Alexa data is useful for comparing website to website, especially when those websites are in the same market (ie: Digg.com vs. Reddit.com)."

Furthermore, as WebKEW, Robin Good and others have noted, "Alexa's rankings tend to be extremely accurate, especially for the top 10,000 sites." 15 of the sites listed here fall into that group. Robin Good actually places the number at as many as 50,000, which encompasses 29 of these Web 2.0 social tagging sites.

So, take these with a grain (or two) of salt, but here are the current rankings:
