For in depth world news and technology trends I listen to the no agenda show with John c Dvorak and Adam curry; their weekly Hunt through the news and c-span broadcasts saves me endless time and the voluminous show notes will be your handy reference too!
Woah, John C. Dvorak is still alive and podcasting? I remember listening to him on Leo LaPorte's podcast back in like 2004 (before I got kinda sick of LaPorte) and thinking Dvorak was the entertaining cranky old man of tech back then.
