I watched all the videos.  The ideas I was able to get out of it have come in handy.  Really helped improve the way I think about writing code, especially for expressiveness.  Even helped me think about the reuse-ability of a few hardware projects.

It also got me interested in stateless languages like Lisp.  Erlang is another language.  Because you can't save a state, you can run things in parallel without worrying about race conditions.  The go through it toward the end of the series.  Interesting idea.  Unfortunately, I haven't had much time to dig deeper into it all.
