This, 10 times. I have such good blogs in my inbox, with easily the quality of the best books I could read, and I don't even have time to go though them. And I don't see any that I'd like to remove - if anything, I'm sure I could easily add to them if I go through each one's blogroll.
The last non-fiction books on the other hand were huge disappointments. Even Daniel Kahneman, to my surprise: Noise had a good idea and was well written, but could easily have been 1/4 of its size or less. I don't have either the time or patience to go through 75% fluff. It feels more and more like books are written for the less intelligent audience, with the abundance of examples and repetitions.
As for the blogs I read: AstralCodexTen, Zvi, MarginalRevolution, Noahpinion etc. They're obviously not everybody's cup of tea since it's about my tastes and preferences, but I dare anybody to say even above-average non-fiction books are better than that.
