For anyone that lives near Atlanta, this was recorded at http://www.meetup.com/atlantaruby/. Our next meetup will be November 14th if you want to hear more awesome talks like this one. </shameless plug>
I've been to that meetup before, very high quality, many talented people, and interesting talks (and lot's of recruiters). They also have a Saturday RoR beginners group if anyone is interested.
