David and Olivia Bisset sat down for a chat with Matt Mullenweg about open source, Tumblr, and how Matt deals with negativity. Matt has three roles today: CEO of Tumblr, CEO of Automattic, and project lead for the next release of WordPress. He shares what went wrong with post formats and what he would love to acquire next if he could. The answer may (or may not) surprise you! Recorded shortly before WordCamp Europe 2022.
