I got on Skype with Rob Spectre, master of Carnivals and head of Evangelism at Twilio. He's spoken multiple times at HackCon, which is how I know him.
We talk about hackathons, how Twilio inspires and equips developers to change the world, Signal conf, and other great evangelists. It's an amazing episode with one of the OGs of evangelism. Listen and learn!
BTW - That pic is of him emcee'ing Twilio's $bash party at Fort Mason in San Francisco. That party was an unforgettable experience, but in true evangelism form I was so drunk I can't remember all of it.
