Wow, I didn't know about the github gem. It looks incredibly useful.
edit: ProjectPlus for TextMate also looks neat. The one thing I missed when switching from SVN to Git was SVNMate (which was apparently the predecessor of ProjectPlus?)
Dav Glass isn't mic'd during the intro - I promise the sound improves.
Fun finally putting a face to your nick :) At the start of your talk you talked a little bit about reviews and even mention a few things such as how many companies only send emails or that you can work in a branch without having to push it to the central repository. This is one area of Git and distributed revision control that I can't praise enough. It raises the code review bar to a whole new level while making it less work. The best example was how with svn/perforce etc when reviewing patches almost no one ever applied the patch to see if it even compiled let alone worked. With Git I nearly always do this because it is so easy. This an other things really improve the quality of the main repository on a day to day basis.
I was in the audience for this talk. Great job guys!
