When I published the previous post I was prompted to share it with Google+.
I had already tried a bunch of stuff to get my main blog (http://radicalbaseball.blogspot.com) to go back to prompting but everything failed. I had suspected this blogger G+ option:
"Use Google+ Comments on this blog".
I had turned it off but that did not seem to matter. In this blog I turned it on and the problem started here, too. I then turned if off here AND closed the tab, re-opened and the problem went away. I then tried that with http://radicalbaseball.blogspot.com and it, too, was fixed.
But what the heck? What the heck is Google doing with junk like that? Oh, and any indication of G+ sharing in http://radicalbaseball.blogspot.com for past posts have disappeared. What the heck?
