I am pretty happy with the preview release of Doppler 2.0.  If you have Windows, you might want to check it out for capturing podcasts.

I am listening to the following new podcasts (not all tech focused):

• Matthew Bischoff’s Esc Radio! [great production, good info]
• Kevin Devin’s In The Trenches (ITT) [great system admin and integration discussions]
• The Point [advanced graphics/audio/video production]
• Mike’s Lifecast [nice sound, has an interesting open source problem]
• NASA Podcast
• Jon Udell (infoworld.com)
• InternetPro Radio (licensed mainstream music)
• Endurance Radio Daily (sports – running, swimming, biking, triatholon, etc.)
• Chuck Chat (tech focused)
