Thank you Jim,
I'll keep plugging away, reading one after another, until day's end. I think some authors rate essays based only on whether the author appears to agree with their views as expressed in the abstract - without attempting to learn whether there are good arguments for that view in the essay itself. I know that I would have been fooled by the summary in the abstract of several papers, because the author turned my head around with skillful debate. That's what it is all about, in my view.
What I don't like are critical ratings without any critique about what was disliked. I'd like to know both strengths and weaknesses in my writing or approach. I guess people who say nothing fear reprisals or are just cowards.
Good luck also to you,
Jonathan
