Jason Calcanis breaks the news (via John Batelle's Web 2.0 conference) that Yahoo has given its blessing to Overture ads in RSS feeds.

Unfortunately, as I wasn't there, I don't know if that means Ads In Feed Posts or Ad Posts in Feeds. I assume it's the former.

This also begs the broader question of whether Overture's Content Match is going self-service for publishers of all sizes, ala Google AdSense and Kanoodle, or if they really meant "just" RSS feeds. Once again, I'll assume it's the former.

Either way, as I pointed out in my post titled "Actually, Google News does make money for Google", it sounds like Yahoo now clearly sees the need to make a land grab for the rapidly expanding blog/RSS advertising "real estate" that's opening up.
