I encountered this post today, the title of which suggests there were 18 more like it. I regret having missed them. Despite the user-hostile web page in which the article is presented, the selection of blog posts is good, and the content summaries useful (I stole a couple of JL Dutaut's recommendations for today's newsletter). (OK, checking in the archives I see that the '19' was a date, not a number, and that different people author these reviews every week.)
