Wikis
I've always disliked wikis, mainly because they seem silly and have a
very annoying name. However, they really are a near-perfect solution for
writing documentation, and as much as I want not to like them, I have to admit
that they really do shine in this area. Aside from cool projects like
Wikipedia, Wikimedia also has a really cool
cookbook. I found this a few
weeks ago, just as I was thinking that it would be cool to have a place to go
and type information about ingredients, techniques, etc. It's really empty at
the moment, so if you know anything about food or cooking, go over and add an
entry or six.
