Via Anu on IRC at blogtalk (and many others): Geeking with Greg: Blogory RSS feeds:

"The RSS feed is personalized, so every reader gets a unique feed with articles that match his or her interests. The feed aggregates weblog articles from thousands of other weblogs, combining all the weblogs into one RSS stream and helping readers find and discover new articles and new weblogs. And Blogory's feed is adaptive, learning your interests as you read articles from the feed and changing the RSS feed to more closely match your interests."
