UPDATE: It seems to be working - I am getting comments from folks who have been missing...woohoo!
To my readers who are having trouble leaving comments:
I've changed my comment section to a pop-up window. Please try to enter your comments again!
The Google engineers are working on this problem. I'll return to the whole 'comments at the end of the post' layout as soon as the problem is resolved.
Thanks for reading! I look forward to your wise and witty comments!
