For me, I actually feel much more motivated to write good and accurate documentation knowing there will be at least one reader who is going to look at it very closely and will attempt to synthesize useful information from it.

Same with my old open-source projects, it's kinda cool knowing that all the old stuff that nobody would have ever looked at anymore is now part of a humanity-wide corpus of useful knowledge on how to do X with language Y.
