There's an entire universe in every single tweet, and it all really depends on the content as far as how it's going to spread.

The idea of Twitter started with me working in dispatch since I was 15 years old, where taxi cabs or firetrucks would broadcast where they were and what they were doing.

All my days are themed. Monday is managementTuesday is product, engineering, and design. Wednesday is marketing, growth, and communications. Thursday is partnership and developers. Friday is company and cultureOn the days beginning with T, I start at Twitter in the morning, then go to Square in the afternoon. Sundays are for strategySaturday is a day off.

Meet customers where they are; question how to make the tools customers use more valuable.

Short term satisfaction will never lead to something timeless.

Making something simple is very difficult.

The Web provides a very easy way to immediately grasp what's going on. It really offers the transparency, so you can see, especially with the search engine, how people are using Twitter at one glance. The phone doesn't allow for that.
