I think i've written about this already, but i would like to stress the coolness and the sheer joy of listening to the insightful interviews that are broadcast on .Net Rocks radio show.

Listen to Dan Appleman(My API Guru) , Alan Cooper(My Interaction Design Guru), Mark Andres(My ASP.Net Guru-God-Creator-with-Scott-Guthrie), Chris Sells(My new found .Net Guru) and lots of others talk about the insides of interesting stuff concerning the technology we work with, the attitudes we use, the psychology behind many things, how some things came to be as they are today .. It's like having the conversation you always wanted with your Guru of choice :).

 I burn CD's of the Mp3 shows(most fit perfectly on an 80/700MB CD) and listen to them on my way to and from work.

Totally Recommended!
