Nice - I was watching this yesterday as it happens. Rob does a nice job with this one I though. Seems like he is aiming at the .NET community though, and with the hoo-ha about win 8 and metro style apps, can't say I blame him - there will, I think, be a massive market for bringing .net developers kicking and screaming into the HTML5/Javascript future. I work with quite a few of them and it's almost as if jQuery, node, backbone etc has passed them by.
