Holy crap, this is one hell of a comprehensive reply. And a great one!
I just want to say, I'm not really an expert on most of the topics I write about. I just love science and think it is the way to change the world for the better. And since I'm a bit too, well, stupid to actually help science as a scientist I chose the path of popularizing science. So I do tend to "dumb down" whatever I read and stuff gets missed while doing that.
And I do skim through many scientific papers a day and read at least two a day. That sadly often doesn't leave me with the time to check up on every single claim in the papers.
But again, my goal isn't to critzize the papers at all
