For tech, I like the 'DailySearchCast', 'TWiT' and anything Veronica Belmont does on CNET. I think Perez Hilton is a riot, and the rest of my consumption is by people: Folks like Dave Winer, Fred Wilson, Mark Cuban, Brian Alvey, Jeff Jarvis, Xeni Jardin, etc.

Hammer down product fundamentals first. Make sure you've got something that works before doubling down on promotion and marketing. Create a groundswell of organic support, and only then leverage PR and advertising to spread the word.
