I wouldn't call Wikipedia "crowd composed" since by all accounts, each given entry is mostly edited by a few, fiercely territorial people, if not by one, fiercely territorial individual. The reports of bullying and fighting among editors there and their hostility to newcomers make it seem almost legendary. It's only the result of a "crowd" because it spans such a large range of human knowledge. But I doubt that there's a whole lot of real collaboration going on among large numbers of people. Sure, it's one large project sharing a URL. But so is Blogger.
