Jason Olson is a programming language evangelist in addition to his duties as a managed (.NET) tools evangelist. You know him from C9. He's a long time Niner and has always been passionate about languages. I've known Jason for a long time and it's great to see him take his passionate intelligence and apply it to both learning several languages and writing his own. This is awesome to see! I caught up with Jason at Lang.NET 2009 where he gave two very interesting talks, one on F# and one on modern object orientation. Here, we talk about his presentations and his perspectives on object orientation, F# and his own language.
