I've been using the Beta version of Stack Overflow and I'm very impressed. Jeff Atwood and his team have done an excellent job with this site and it's already provided me with some answers to questions that I had and those answers were furiously fast and accurate. I hope the quality and speed continues when they go live.
I've just caught up with the Hansel Minutes podcasts so I've started listening to Stack Overflow's podcasts. I've listened to the first 3 so far. To start with I wasn't that excited by them but by the end of the 3rd podcast they've started to grow on me and I can see myself listening to them on a regular basis.
Talking of podcasts for programmers, my friend and co-worker Saul Mora has just published a list of techie podcasts that he listens to.
