I've had this option for some time now, and today it has been giving me problems all day, especially with Publicize to Facebook. I've connected/reconnected numerous times, and made new posts, and everytime it would ask me to authorize Facebook - so 7 of my latest posts have not loaded to facebook, and I'm still 'Authorizing' it.
Another blog of mine gave me problems with Yahoo - and asked to contact the website (wordpress).
I hope that it's just a glitch, and could be fixed soon. Thanks
The blog I need help with is xenianova.wordpress.com.
