I interrupt your regularly scheduled monday to say that I’ve tweaked my comment settings in hopes to help those of you who have mentioned the inability to comment lately…
I'm not noticing a difference, but I haven't been having any trouble commenting lately. As a reader/commenter, I did figure out (when I WAS having trouble) that if I UN-CHECKed the "stay signed in" option on my Google account (when I'm logging in so I can leave a comment with my Google ID), for some reason I was able to actually log in & leave a comment. Counter-intuitive, but that was the problem. Someone on the Goggle team needs to fix that.
Rainy Day in May... 
Let's see if this works!
