Newsgator Digs Into RSS Usage Patterns to Solve Info Overload

Bud Gibson says that Newsgator - a popular RSS aggregator - has hired a taxonomist to use its Newgator Online feed archive to create user profiles based on usage patterns. According to the post, this would help Newsgator better target consumers using a sort of collaborative filtering approach. Newsgator is also considering adding folksonomic features. I wonder if Newsgator will also use this data to try to court advertisers via behavioral targeting. (Via del.icio.us/tag/micropersuasion)
