It's funny I used to have Google Reader filled with dozens of blogs but I don't regularly read any of them anymore. Tynan's only because I get an automatic email now to my personal inbox.
Sebastian is really good stuff though
Tim Ferriss, particularly his old shit and guest posts are really good
Podcasts like Smart Passive Income, HBR IdeaCast, Radiolab, Buddhist Geeks
And then if I'm looking for something in particular then I'll go to the old blogs I know that have good content. Ramit's if I'm looking for career advice. Lifehacker if I'm looking for the best XYZ software.
Otherwise it's all books. The best thing a blog can probably do is refer me to the really good books or write a summary of the book so I don't have to read it.
Some oldies from my reader
Early Retirement Extreme was a pretty ffascinating blog that's one of a kind.
Seth Godin's blog is good if you need a kick in the pants in the morning
Cool Tools if you want to waste time looking at awesome gadgets
