Well he is a "professional Indie developer" and he'd probably take umbrage at being called non-professional ;-) I'm a professional Indie developer, because it's my profession. It's your profession if it's your main job, even if your games don't sell and you only make £1 a month. If you have a "day job" and you make Indie games for a hobby then I guess it's not your profession. However, whether your games *look* "Professional" is an entirely different matter and is not related to if it's your job or a hobby. Hey I think we had this debate before sometime in the past...Sorry to be a pedant ;-)
Maybe people view "professional" as someone who works for a big company and makes AAA games?
