HelloMovies.com is a pretty neat community-based website that I've been playing around with. It's a really smart and thorough aggregate system that allows you to search for movies based on "tastes," genre, release date, language, awards, what your friends liked, and so on. It also calculates how many hours of movies you've seen and the percentage of which movies you liked, and which movies you might like based on your ratings. There's a lot of user options -- you can write reviews, link to your reviews on a different site, upload posters or trailers, and lots more. And, of course, you can earn points on a level system, which will eventually earn you free goodies.

One of its more interesting features is that you can browse movies that are already available, rate or add them, and then watch them immediately -- for instance, the page for Dance of the Dead allows you to watch it for free on FEARnet, rent it from Netflix, or rent it from iTunes. It also pulls info from IMDb and links directly to that movie's page, and has info on any award the movie's won and so on. Naturally, it also can jack into your Facebook account (aka Skynet), and has some Facebook-like features like a "wall" for your buddies to post on.
