I use backloggery all the time now (http://www.backloggery.com/knightdriver). It's my second favorite site after Pixlbit. It's really helped me organize what I own and push me towards completing everything. I don't list everything I've ever played but just what I own. If I play a game and don't like it or know that I will never revisit it, then I trade it and take it off the list.
I use the Wishlist a lot now too. It's a great way to keep track of all the stuff I want to get.
My favorite part though is Fortune Cookie. This is a randomizer that helps you pick your next title to play. I think it's really fun. It's become a metagame to my usual gaming. The site is really well designed too, just like Pixlbit is. Those two should get married.
