The same with RFCs and W3C documents. All that stuff is written very well, from the technical view as well as regarding their readability. Why putting a layer of blogs and websites around them, which actually lower the perceived quality?
Also, I'm frequently annoyed by articles that write about what some other people (e.g. RMS) wrote. These aren't much shorter than the source article, and aren't written nearly as clear as the original.
I appeciate it when an author just links to the source and elaborates on that topic, stating his own opinion, and perfers to quote rather than to paraphrase what's already clearly written in the source article.
