Maybe it's the inherent academic in me that recoils in response to a group project like a wiki. Where's the validation, the citiations, the peer review? They look great and many seem to have a lot of information, but how much of any of it can I believe? When I look over even the Extension wikis I also start to wonder who will ever find this information? The sheer volume of information out there boggles my mind.
Wikis didn't do anything for me today. Was it the wiki or just where my head is at? Today I will have to leave that question alone, unanswered.
