This is a startup? Your About page freely admits there's nothing special about it, so what are your plans?

With no focus/theme for the questions other than tagging, I can see the front page having a very low S/N ratio if this gained even a fraction of the number of questions Yahoo Answers and Stack Exchange sites get.

The Stack Exchange sites have shown that having domain knowledge bleed over into other areas can be very beneficial, so I think you'd be better off giving the site some sort of focus/theme. Easier to market and more interesting for the users. Good luck.
