So I never really thought about a wiki's uses in other forums. But of course, its weakness when fact-finding (anyone can publish their so-called "facts") is a strength when you are actually searching for opinions and suggestions.
And I've always known that -- I just didn't know that was a wiki. Poor wiki. Scandalized by it's infamous cousin "ipedia."
I love the idea of using it for lists of favorites and suggestions. For conferences? I don't know. I wouldn't want to rely on it for actual important facts like What Time Is Lunch and Where. I've known too many people who give strangers made up directions to places in a attempt to be helpful, i.e., "The bank building? Oh, yeah.....um, head up to that KFC and take a right. Then go straight. You can't miss it." (Is that a Southern Thing? Too polite to say "I dunno"?)
