I use Wikipedia for some basic research for library customers, because it goes directly to the requested subject and so far it as been helpful. I think online community websites are ok for maybe team members, groups, staff, organizations, but for everyone to have access to add or delet this could be a problem. With spammers, people with malicious motives, and pranksters. To have a online community without registration or doing some can of check to make sure their not some kind of "nut" would be advisable. Some people really rely on that information and use it for education, profession and self knowledge. It should be supervised before posting, they maybe giving false information. I know wikis is for quick information, but somehow we should make sure it's valid. But that's me. Google is good, but sometime it may have 2000 :)) links to the subject or question.
