Thing 12 WIKI

I watched the video and understand what a WIKI is now - sort of an interactive blog, faster than waiting for individual emails (but I still like those --more private and intimate - the whole world doesn't need to know...)anyway I see where WIKIs are valuable. What I don't like is that they seem to be a forum for people who want to talk but don't have much to say and you have to muddle through that stuff to see if there is something valuable in the middle. (Kind of like when someone hits reply all on their email, but it's really only directed at the sender yet we all get the message :(. Guess I'm not sold.
