I probably don't qualify because I do put in 40+ hours a week doing this but it's not my fulltime job, atleast not yet (started out March 2006). I still teach english 10-20 hours a week, and also develop software on a freelance basis. Now if I could only get the time to start up that ebay thing...
Then again, if we do move to San Francisco next year as planned I might just try my luck in the Silicon Valley instead. Still, I hope I'll always have time to build and submit a freesite a day.
