Twit.tv if you haven't checked it out, go check it out
I can't remember how I stumbled upon Twit, but I am glad I did. Its a great network that has tons of podcast's for every niche. There is a daily tech news show, along with shows like macbreak weekly, This week in Google, Windows Weekly, Android news, Ipad stuff, etc. Also, Joshua Topolsky is on it from time to time, including today on their weekly show Twit, which covers tech news for the week. Seriously, go check it out, tell your geeky friends, and tell them to tell their geeky friends. There is a lot of high quality shows and the best part is they stream everything live. I am sure you have heard of some of their hosts, Leo Laporte (main guy), Tom Merrit, etc.
