A parallel statement could be said about Wikipedia. I bet if you're a world-class expert at something, probably the last thing you want to do when you get home after a hard days work is log to Wikipedia and edit articles and deal with mods. Still, Wikipedia manages to maintain a not-bad-for-a-first-try quality level on most science-y topics.
