Have you heard of "Wiki"? If not, THIS should explain it.
It's a pretty cool concept - very "open source-ish". I just came across a site for .NET interop with native Windows functions (called P/Invoke i.e. Platform Invoke) - http://pinvoke.net/. You can actually add content to each function just by double clicking anywhere on the page.
There's even a wiki encycopedia called Wikipedia.
