To Wiki or Not to Wiki

I know some people who were thinking of starting Wikis for various work-related functions. Here's an interesting post from BusinessPundit about possible Wiki pitfalls.

Wikis aren't about sharing. Wikis are about simplicity of editing and
centrality of information. In a case where random collaboration wouldn't work
without a wiki, it's unlikely to work with a wiki. What the LA Times should have
realized is that they were giving people an online soapbox. Then they should
have asked themselves this question - if we put a bunch of random people in
front of a large audience, let them remain anonymous, and let them say whatever
they want, would we get a positive result? No? Then don't do the same damn thing
online.
