As someone pointed out, there is a wikipedia page on U2 already - people here can update it (or copy information from the site that is missing there).
A structured environment has some payoffs (think "the Apple experience" though it's far from perfect), we agree that we're lazy and don't really bother with content with everything going on in our lives, and we're going to make a solution where there is still some oversight and controlled navigation etc but people can contribute content to make things work faster.
