In fact, that's one of the reasons I'm working on building CastingCode.tv (http://castingcode.tv) as a platform to serve both ad-hoc and organized live coding events to the web. :)
Are you the same creator as vimconf? The sites look alike and so did the emails (subject atleast, did not open). Are you the submitter of this? Why two different usernames if so. And why promote them both??
I am indeed the same person behind both CastingCode.tv and VimConf. However, I did not submit this VimConf article to HN. That was done by somebody else and I had no idea it was being submitted, so it took me by surprise.
