Today we caught up with Charlie Cheever, the founder of Expo, an open source toolchain that helps people build native mobile apps (which we're using to build Spectrum!). In this episode we dig into the Charlie's path to working on Expo, including building calculator games, building Facebook Platform, co-founding Quora, and so much more.

We've also got a big announcement: we're building a new thing for you! It's called Spectrum and it's a place for the community to hang out and share what's going on in design, development, and anything else you might be interested in.

We're still in beta, so expect bugs and lots of improvements over the next few weeks, but in the meantime we'd love to hang out with you and chat!

Sign up at Spectrum.chat, join the SpecFM community, and share feedback in our Spectrum bug report channel!
