Makes sense.

The big limitation of social aggregators is that they're self-selecting. People who come to the site are influenced to return based on what they saw here. Small biases in the tastes of the initial userbase get magnified.

I tried to solve this problem a year ago by building my own crawler and crawling 2000 RSS feeds. I could show anybody content independent of the tastes of previous users. But I never solved the problem of quickly figuring out a new user's tastes.
