I understand that Stack Overflow is the gem in Stack Exchange's crown, but does anyone else feel that the Stack Exchange community is only used by people who are programmers? There are a lot of great site proposed in Area 51, but it seems that they are held back by lack of interest by programmers.
Pets for example it would seem should be a huge site considering that it is a multi-billion dollar industry and that almost a third of the population in the United States alone owns one or more pets. Yet this proposal has been in the Commitment phase for eight months. I confess myself that I would have had no knowledge of any of the other Stack Exchange sites if I hadn't found answers to programming questions I had during work.
Is it a lack of marketing that non-programming people don't know about Stack Exchange or is it just 'too made' for the programming community? Or perhaps something else? Is there a way that Stack Exchange could grow in a new direction to be known by the rest of the internet surfers in the world?
