I have a few text files at work that I keep track of things. I treat it more as a reference file/personal FAQ file, some notes are verbose and some are terse. When I am learning on a side project I keep my notes in Google docs. I take the time to format those notes better so I can study them easily. Google Docs has history and warns you when you delete a file. What do you use versioning for? I correct my notes when I discover they are wrong, and if we release a new version of the product, I just record the new behaviour in addition to the old behaviour (along with dates, build numbers etc)
