For what it’s worth: It appears that I can no longer post comments to my own blog. I get an “bX-rynfwe” message, whatever that is. Others who report that error message on Blogger’s forum appear to get no satisfaction. So, as much as I would like to respond to some comments, I am not able. Hopefully, the problem will go away as mysteriously as it appeared.
Update: Larry Gross has reported that he cannot post comments either.
