25 Largest Web 2.0 Sites

25 Largest Web 2.0 Sites June 2007 eBizMBA:

"eBizMBA's monthly survey of traffic data for the top 25 largest web 2.0 sites ranked by a combination of Compete and Quantcast data. For each site, we show unique U.S. monthly visitor data as well as respective rank. For entries where a wide range exists between the two data sets the highest numbers were used for ranking purposes. Although no traffic metrics are completely accurate we do believe the data below to be useful for gauging relative audience size."
