I am having some issues with Facebook sharing. My stats of followers, who use (Facebook via) Publicize to access my blog, have disappeared. They used to show up alongside my regular blog followers.

There are clearly a ton of problems with WordPress.com right now, including RSS, scheduling, publicize, adblock, browser incompatibilities, etc, etc. Staff are probably getting around to the problems in the order of severity, which means they’ll solve the “i can’t post” problem first. If you have reported it to them via your dashboard Help button, it’s in the list.
