Well damn, maybe I'll do one. Hell I'd get together with people in SF or wherever for free and show them how to do stuff. It'd be an awesome bad ass way for me to get feedback on what needs to happen to make Mongrel2 awesome.
i second that. not just mongrel2, even ruby, jazz guitar, etc.
i think being able to get feedback from someone like zed allows one to QUICKLY and EFFICIENTLY get to the meat and heart of ideas and concepts. whereas in my experience with other instructors you're sometimes wondering in the back of your mind whether the person actually knows what they are talking about.
it's similar to being able to study directly with a zen master. except in this case it's not zen, it's zed.
