As a general note, the content on the TWiT network is superb. I love the great ethics conversations that are had on TWiG (This Week in Google). I've loved listening to the "coming out of the wilderness" progression of Mary Jo Foley & Paul Thurrott with regards to Microsoft on Windows Weekly. And Security Now is my guilty educational pleasure, as its greatly expanded my knowledge of security issues and topics, which have served me well over the past few years.
