Ask Bagginsbill why he's been giving away shaders for years and posting in forums to educate users, despite the huge amount of time both of these endeavors involves. It surely wasn't in order to prove his cred so that he could become a best selling vendor. But I have trouble seeing the work he produces as being that of a "mere hobbyist" just because (with the exception of his recent contributions to the marketplace) we don't pay for it.
