The point I was trying to convey was that contrary to a chronological or genre-based list, MovieLens allows you to build your profile faster by showing you movies you might have watched (and typically liked, given that people rarely watch movies that they know that they'll despise a priori). Regarding your last point --- exportability of the profile/rankings --- I find it immensely important and one of the reason I do not use (or make minimal use of) services like Facebook, sync.gr etc., but prefer open solutions such as FOAF, RDF etc. Well, MovieLens sorts movies based on its prediction of your grade, so, in this sense I did get some movies I’d watched but didn’t like too.

However, from my limited experience I've noticed a "movies I've also watched keep coming up as I'm applying ratings" trend. In your MovieLens review you mentioned you noticed good movies you've already watched coming up; I'm talking more of a mixed bag (i.e. I was given movies I've already watched, but I certainly didn't like all of them). Do have a look at their site though; their raking & matching algorithms (TCIs, etc.) are explained and you can easily realize that the math/logic they're using makes sense. Oh, and they allow you to easily export your rankings in a variety of formats (XML, HTML, text) which makes me like them even more. I do realize that exporting your movie rankings isn't exactly critical and it's probably of no use (quite the contrary to, say, your email messages) but it tells something about the site's philosophy -- something that I like.

I hadn't heard of it. Have you used it? Is it good in its data clustering/recommendations? Thanks for the pointer Konstantine. I hadn’t heard of it. Have you used it?
