Why Wikis are Cool

I take a lot of walks. I live in a city. I find a lot of neat stuff as I walk (chairs, 1st edition rare books, antique typewriters--no lie). However, as cool as these are, they must have a use, otherwise I don't allow myself to take them back back to my small studio apartment. The following video is like that--like finding an beautiful Eames-esque lounge chair that I just can't take home because I don't have a use for it yet. Unlike that chair though, I can pass this wonderful thing to everybody else and can come back to it when I do need it. Common Craft, who made this video, is so cool! Now I actually want a group project just so I can create a wiki.
