Jeff Atwood is the co-founder of Stack Overflow and the Stack Exchange network of Q&A sites and in 2012 started his company Discourse to build software and services around better forums.

In September of 2017, his son got a yo-yo and Jeff was instantly hooked, playing with yo-yos for the first time since he was a kid in the 1980s, and it quickly became an obsession and a collection with hundreds of yo-yos. Recently he's been sending out gift packs to everyone he knows online and we talk about how he came to yo-yos, what's great about them, and why he's spreading the gospel of yo-yos to anyone who wants to listen and try.
