Professionally - I took over the monthly payment system at my current job. There was a fair amount of technical debt and tribal knowledge about the thing - the first few months, I took extensive notes about everything from basic usage to problems encountered. As I paid off the technical debt, however, I was able to gradually turn the notes into code; now, it's almost at the point where there's nothing to write down each month (although there's usually new code to write). Outside of that, a friend of mine has made his own semi-public wiki, and tied that into his email client; he can now easily link to pages from within the email, allowing him to communicate A LOT with very few new words. It's pretty neat.
