The Kindle Developer's Forum has been using it for a long time, as a place for people to index information, tutorials, etc. where everyone can keep track of it, and easily contribute.
Wiki pages are best for this, since you don't have to rely on one user to maintain an OP, or force people to read through dozens or hundreds of pages full of posts.
