I am a really huge fan of nicely formatted and presented documentation. Sometimes I can get a little too OCD about this. If you haven't reviewed any of Google's coding style guides you should, they have a lot of nice information in there, and their views are worth considering. Lately I've decided to try and conform to their C++ guide a bit, but perusing through their doc was just ugly for offline viewing. It may not matter to most people, but I made a slightly cleaner version of the 3.274 revision of the guide in PDF format.
