It's Facebook for studios!
Aside from actually facilitating the creation of music, the best thing about owning music technology is being able to show it off.
Gearjunkies Userstudios is a site where computer musicians can create a virtual representation of their home studio by piecing it together from lists of available kit. It's also possible to upload pictures of your set-up in all its glory, which makes it the closet thing we've seen to a Facebook for studio owners. Thankfully though you won't have to put up with the vampire applications, friend requests from people who you've never heard of and pictures of yourself looking worse for wear.
Incidentally, if you're the social networking type, come on and join the Computer Music Facebook group. Search for "Computer Music magazine" to join in the fun!
