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?".
