A more valuable service

From Slashdot, a link to a community-based book recommendation scheme that actually might be useful. That's because, rather than looking for strong positive correlations, it's doing the reverse: finding books that you shouldn't bother reading:

Unsuggester takes "people who like this also like that" and turns it on its head. It analyzes the seven million books LibraryThing members have recorded as owned or read, and comes back with books least likely to share a library with the book you suggest. The unsuggestions come from LibraryThing data, not from Amazon.

Update: LibraryThing appears to be "slashdotted" at the moment. If you're finding access slow, try again later today or tomorrow . . . the /. locust-crowd should have moved on to new pastures by then.
