I do my best stuff midmorning and superlate at night, from 1 to 5 in the morning. Some people don't need sleep. I actually do need sleep. I just sleep all the time. I'll catch naps in the afternoon, or I'll take a 20-minute snooze in the office - just all the time. Our business is 24 hours. Our guys in Europe come online at midnight.

One of the things I've been working on for the past few months is a radical simplification of the interface.

The relationship between WordPress and Tumblr has always been pretty friendly: Tumblr's own blog used to be on WP, WordPress.com supports Tumblr as a Publicize option alongside Twitter and Facebook, our Akismet team sends them daily emails of splogs on the service, and there's healthy import and export traffic both ways.

You can't build everything and there is no more a killer feature. Everyone has a different killer feature.

Usage is like oxygen for ideas.

Get the 1.0 out as soon as possible...even if it sucks.

I don't care how someone lives or how good their spoken English is. I do all of my interviews on Skype text chat - all that matters is their work.
