I just watched this. Karl Lehenbauer gives a basic intro to the language, making comparisons with Lisp, talks about his own development as a software engineer, and how his company FlightAware uses Tcl for most of their code. I found his personal history the most interesting part, there were lots of things there that made me think: yes, been there, done that :-)
