Thanks! An English speaking country is certainly a good idea (as I am most comfortable with English, not counting my native Bulgarian). And you are right :), I have friends working in Ireland, so it won't be a problem to come there and stay at their place while working on initiating a company.

I agree with all you said about Silicon Valley. But we are already a nice team here. We have several "hobby" projects (which all failed back then) behind. And now we are going to do it "for real". Of course, we may be moving somewhere else in the future, especially if we come to the need to hire more people. But for now we are just going to live cheap in Bulgaria and work :).
