Earlier this year, we passed an interesting milestone at Air Mail: the one millionth member signed up. Now, this isn’t an active user count metric or any sort of important announcement from me. I just think it’s a cool round number that I’m proud of.

I’ve worked on a number of large, high-traffic applications–many with more users than this. But this one feels different. We created it from nothing. Just an idea born in a tiny ground floor apartment in the West Village.

It’s a fun accomplishment to build something that you’re proud of and that there’s a million other people out there somewhere that think it’s cool enough to sign up for too.
