Ask HN: My startup is launching in a few weeks and I'm terrified. Advice?

Me and two friends started a company right out of college developing a new social news site that we had an idea for. The thing is, when we started, none of us really knew how to program, at least not anything more sophisticated than simple scripts. So over the past 10 months or so we've been working on our site and developing our skills and are close to having something we can put out there.

However I am still very self conscious about our inexperience. I constantly worry that we're making rookie mistakes that will lead to serious problems with our service. Or that we won't be able to put out fires effectively enough.

What can we do to compensate for our lack of programming experience?
