Besides search engines, what generates the most traffic for news websites? Other news websites, it turns out. CNN.com, MSNBC, Fox News, the New York Times, and NBC's Weather Channel rank in the top 10 traffic sources to the news and media category, according to Dougherty's study.

Techmeme's Rivera argues that news organizations complaining about aggregators aren't just wrongheaded -- they're hypocrites, too, he told CNET News:

[The] WSJ (a News Corp. property) and NYT (a key AP member) are both themselves news aggregators. Both maintain sections which quote headlines from external sites. So, constituents of these organizations already know aggregation is useful and fair. This knowledge just hasn't reached AP's and News Corp.'s leadership.

The implication: The newspaper industry's real problem isn't that sites like Google News and Techmeme exist. It's that they don't own them.
