M Kennedy: How did PayPal and eBay adopt Python so broadly? There was this history, and some of those people moved on to do minor things like YouTube. And then, it sounds like you guys are doing a lot of Python stuff now, right? Oh, yeah, absolutely. So, I mean, basically every aspect of PayPal, and this is like a large business with many different concerns. "Even some web development and web service like front-end type stuff is going on as well," says M Kennedy.
