By recommendation engine, I mean a web app where you tell it your favourite things, and it recommends other things that you might like, based on a corpus of data.
Apparently Netflix does this for movies (I don't know, I live outside the US).

...but it looks like they've all since disappeared (kindakarma, wikilens, a few others I think).
Can you save me (and future generations arriving here by google!) some hours of searching and recommend any good recommendation engine web apps?
Particularly looking for video games, but any will do.
