My mother is a "admin assistant" at work, and she does "admin assistant" work at home for two clubs she's part of. And a month ago a bus driver I know drove me and some relatives around for 6 hours just for the heck of it. And journalists do write for fun, ever heard of blogs? And my brother as a mechanical engineer recently fixed some headphones (they were cheap for 20 bucks or so, so he could have bought new ones easily).
While it seems that only hackers do that, everyone does it more or less as long as they are passionate about their jobs. They just aren't as visible as the hacker crowd that develops Linux as a hobby.
