I suggest reddit.com/r/programming, Hacker News obviously, and YourVersion.com for finding new stuff to read based on your interests, and then you can usually find more to read without too much trouble. There is always more!
Two of your links don't work. The first post is interesting, but I think the Crockford book is a much better read. Norvig's articles and wikipedia are of course awesome! I don't count them as blog posts though.
The other point you illustrate is that most reading on the internet is scattered into bits and pieces. Going through all of those topics in one morning is too much, for my brain anyway. I'd much rather read on one of those topics at length and work out some problems and code. Reading small posts here and there may make me feel smarter, but I'm not convinced it actually makes me smarter. I ask myself, "How does knowing this change my expected behaviour or my anticipation of the world?".
Offtopic: badave, I used to work on MeeHive, which is similar to yourversion. I'm now off on my own building a tool to help me read more widely. Would you be interested in trying it out? My email's in my profile. I'd love to hear about what you think is missing in google reader, yourversion, etc.
I don't know if you can read 100 good things daily, but you can easily get the equivalent of 20 really good books a year just by reading occasional links from Arts & Letters Daily at http://www.aldaily.com/.
