Like everyone has said - this is a good site and this is my default place to go now.
features I really like:
showing our collections and wishlists
marketplace (thou I wish it was used more
There have been alot of good ideas but one thing comes to mind. Any way to get access to little pinball video games on the site? Something like visual pinball or something. Might be an interesting way to make use of the credits we get for posting Scores could be displayed. Man I would never get anything done at work...
