That's what I'm thinking at the moment. It won't cost me much to get to that stage and see if the interest is there - if I can get a few contributors in, then I can at least build up the library and basic functionality and launch the main site with minimal cost. If it works, great - I can go from there, if it doesn't it's a bit of a shit, but I haven't wasted a lot of money and can still try out other ideas.
