Parker Snyder aka iToast is working on a podcast aimed at techies, and with some emphasis in Sysadmins.
Besides the current and very good Casting from the Server room, this would be the only other podcast that I am aware of that targets Systems Administration in some fasion.
Last night I spent about 5 hours chating to Parker on his live Ustream, which was also recorded for use in the podcast. The podcast should be done by this evening, and I am looking forward to it. RSS feed should be back then aswell, I will post about it here.
I also encouraged him to ally himself with the Friends In Tech network, as any admin podcast would be a natural fit there. He could also easily get other co-hosts to feature on the podcast.
I hope this works out, it would be nice to offer the tech community another admin-oriented bit of media, there are so few out there.
