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.
Search folks don't understand editorial. I'm not afraid of editorial costs, just like machine-search folks are not afraid of computer servers.
I find very few folks are watching their Facebook feed, some are watching their Twitter feed, and all of them are watching their email box. So, while social networks are nice, email is still the killer application.
Back in the '90s, folks were not sure if they could trust the Web, and frankly, a lot of the services back then didn't provide massive value.
If folks focus in on a niche and own it, there is a good chance they could make half a living from blogging.
