miguel de icaza can talk. nice performance and best promotion for open source i have heard so far for users who don't give a damn to the ideological tingltangl. he didn't talk about mono, but it wasn't the audience for that anyhow. better to look at miguel tells it all

Miguel once said, "There is a point in your life when you realize that you have written enough destructors, and have spent enough time tracking down a memory leak, and you have spend enough time tracking down memory corruption, and you have spent enough time using low-level insecure functions, and you have implemented way too many linked lists".(out of mono weekly)
