People who make heavy use of a language are in a good position to vent about its shortcomings. Sometimes a language is the best tool for the job despite its many deficiencies, and I'd much rather read these kind of rants by someone who knows the language inside out. I hate PHP more than I hate my own mother, and yet I still chose it for my most recent project. Every programming language has shortcomings, it's just a question of picking the best shortcomings for the job.
