I've long thought that a StackOverflow for photographers would be a great resource... but not a business. Unfortunately, the StackExchange pricing assumes that you will be a revenue-generating because no one can justify $129/month on running a free resource.
Photographers are actually a really monetizable audience compared to most. Sign up with the right affiliate program, and a single sale could cover that $129.
I was thinking the same thing ... but I think you could monetize it ... at least I think I could (by putting links to our products on the side, I could make up the hosting cost easily).
