As I’ve explained in earlier pieces, I periodically post “most popular” lists of websites or books that I think educators might find useful. Of course, there are a number of ways to gauge “popularity.” I just view these lists as opportunities to check-out some new sites or books, and find it interesting to see which ones might be particularly “popular.”

Today I thought I’d share a list of the Top 15 Most Popular Web 2.0 Websites.

Actually, I’ll only list the top seven here, and suggest you go to the site of the people (eBizMBA) who put it together to see the rest of them (they did the work, after all).  They say they used  “a combination of Inbound Links, Alexa Rank, and U.S. traffic data from Compete and Quantcast” to come-up with the ranking. Here’s the link to the full list.

Here are the top seven:

1 | YouTube.com
