Changing the world is cool and all, but the real reason to go after this job is to work with Ben Kamens and Jason Rosoff. Kamens was the big boss of engineering at Fog Creek when I interned there and is the most humble and capable developer I've met. Jason Rosoff was also at Fog Creek with Kamens and is the kind of designer a developer loves to work with.

So, Web Ninja Rockstar Badass Developers, apply. DO IT.
