Google.com has an algorithm. Regator.com has Kimberly Turner.

She’s 33, an Atlanta magazine writer, and curator of blogs on the young, Decatur-born aggregating Web site. On an Internet increasingly filled with noise and fluff, she sifts through hardly updated, long-forgotten, navel-gazing diatribes to find good writing and interesting discussions. She shuffles the best into categories on Regator, making it easier for users to find quality posts sorted by topic.

Excellent coverage of Regator from @jamieg at the AJC!
