If I'm doing something for free, I don't mind doing it for free (obviously). If I'm doing something for money, I want to be paid my going rate; otherwise, either find someone else or sell me on just volunteering. I'd never charge $20/hr for software stuff -- it's basically $0/hr (which is most of my time, by choice) or market rate. It's actually the market rate billing that free me up to volunteer with open source projects in the first place.
Studies back you up and suggest "Pay enough or not at all." Paying below market rate tends to just piss people off and make them feel insulted and undervalued.
Oh, good god. If I really thought the question meant the person was being lazy or something, I simply wouldn't have answered it. I'm well aware that if you know what to search on, it can be easy, and if you don't, it can be impossible.
I did the search, found lots of stuff readily available, shared my exact search phrase so it could be replicated and explained my reasoning for sharing the search phrase instead of a link. And now two people are busting my chops for actually being helpful.
I bet no one would have said a damn thing had I simply not bothered to reply and, in this case, not bothering to reply would have been the jerk thing to do because it would have been unhelpful to someone actually sincerely needing help and it would have been done on a bad faith assumption.
