Gotta get my money, gotta get paid

I was told today that for all my help on Blogger's development list, "Google should be paying you for this" ... and then I thought about it -- I always wonder why so many people would be willing to do software for free when it makes so much more sense to get paid for it. Examining my own motivations, I guess it was just "for fun" ... that's a bit sick. I definitely wouldn't do it for free (or for fun) if I didn't already have a job!
