These can be precious, though. I took care to date my comments (an intellisense script does that nowadays, using datetime() and sys(0)), so I'd have at least some context for myself.

The best example for that I had in, I guess, 1993, when I was asked by a customer to add the rebate option to one of their special kinds of invoices (and they were all special :). I immediately remembered that I asked three years before that whether the rebate is taken off before or after tax (I know the latter doesn't make sense, but hey, I've seen that applied and I knew why I was asking). Pulled up the source, and there it was, the comment in the place where rebate should have been calculated, saying "* 23.06.1990 {guy's name here} said that mill invoices will never have a rebate". Just showed the line to the guy and he said "I know, I know...".
