Why am I unable to comment on the Wall Street Breakfast?

I'm having increased difficulty lately as described by OP: the SEND buttons don't seem to register my clicks and today I got five different CAPTCHA prompts in a row. I don't think my intellect is THAT dim yet.

Above problem is ongoing the past week for me including today. The button that doesn't work for me is called "PUBLISH" -- I use Firefox 59.0.2 if that's any help.
