That was a good podcast, I learned a lot. But too bad you couldn't answer every single question that was submitted :( Still, thanks for this episode :)
take 45 minutes and listen to this http://boards.polycount.net/showpost.php?p=1019462&postcount=74 subscribe to the podcast. they are all very helpful, informative, and entertaining.
Two personal favourites; www.faveup.com www.greyscalegorilla.com - technically motion design rather than straight graphics but still a fun blog and some awesome podcasts too.
