One of my favorite Web sites in the WHOLE WORLD was created by a really nice guy who, after running it himself for a few years, wants to find "an active administrator, someone who will respond to feature requests, strive to keep the site up-to-date, give it a shiny new web 2.0 look, etc"
Listology is a repository of user-generated lists. Right now, the site is pretty plain-text, which is one of its appeals. It loads fast and is easy to update. It's also very Netflix-friendly. It's the home of the Netflix Tracker, where I keep track of all the movies I get from Netflix and what distribution center they come from. Listology is also where I share my Netflix Queue with the world. Listology is a great place to go if you are looking for ideas for your queue.
