I want to congratulate Nick especially. There are only a few examples of software this broad being written by essentially one programmer and this is the biggest application he's ever built and the biggest audience he's ever had for his work.
He's a very good programmer, and I told Nick in December when we started the project again from scratch that if he wasn't in I was going to give up on not just this new software but the whole company I founded to run this site. I meant that and the day I met Nick (I actually hired him for my last day job) was the day that a2k's growth became possible again.
Remember how it was 3 years ago? I wasn't building on the old platform anymore, it was often not even working? What changed was that Nick and I together could do something that neither of us could have done on our own. I am not a programmer, and had experience mainly with the architecture and design. So I was limited to largely hacking at other software that wasn't working for us. Nick is a great programmer who works well with a software architect and meeting Nick meant that we could actually do this.
It ended up being a much harder job than we thought, but I can absolutely guarantee that Nick's the only programmer I have ever heard of who could have done this particular project.
You haven't seen the last from him, and there are a few other guys (like Monger, who's writing a technical book right now) who we hope will join us soon.
