You can read about it here Keep in mind this ranking only applies for today, as the traffic count is updated daily. The current Top 10 sites are: Yahoo! Microsoft Network (MSN) Google eBay Passport.net Amazon Microsoft Corporation Myspace Google UK AOL It's interesting to see that the top three are the sites that are pretty likely to be a person's Home Page, thus giving them traffic anytime a web browser is opened. It's noteworty that TB traffic died down significantly in August/September. My initial guess would be that all of the students going back to school started visiting a lot less. It's also notworthy that it seems that traffic spikes just at the end of the month, i.e., the end of October, the end of November, etc.More info.
