There was just a HN story asking about non-developer success stories (sorry don't have the link, writing this using the HN iPhone app) this is a perfect story for that discussion.

A large % of companies were started by non-coders, and this is a good example of one. Not to say anyone can solve hard technical problems but just because you can't code doesn't mean you can't start something great.

There is nothing wrong with starting a business in a traditional industry, the most important thing is doing something you love and want to do.
