For every new feature we add, we take an old one out. A lot of big sites don’t do that, and it’s a problem. Twitter started as a beautifully simple product, but it’s now going the same route as Facebook. The drive to innovate can overencumber and destroy a product.

Tumblr was simply a tool for anyone to make a blog like mine.

We've tried to keep as cheap and lean an operation as possible.

Our team isn’t changing. … And our mission – to empower creators to make their best work and get it in front of the audience they deserve – certainly isn’t changing.

Where I feel the most productive and engaged is when I'm buried in code, buried in some project, tweaking some designs. I'm certainly introverted.

I'm very antischedule. Except for board meetings, I don't really schedule things or keep a calendar. I think appointments are caustic to creativity.

You guys are more talented than anyone in the Tumblr office or in Palo Alto or Sunnyvale. We're constantly in awe, constantly in service.
