Word Considered Harmful.

The title is a bit of an overbid, I must say, since many of the criticisms are rather narrow in scope. For a single user creating a static document for one off publication, Word is still a pretty good tool. (Said through gritted Microsoft-hating teeth.)

But it's true that for collaborative work, a wiki is a better fit - take a look at MoinMoin.
