In an attempt to streamline our site we've decided to give JetPack publicize a try. Previously we had been using MailChimps Social plugin to broadcast to two of our Facebook profiles, our Facebook Page, and Twitter. We liked that Publicize offered Google + and Tumblr as options in addition to Facebook and Twitter.
I tested it last night with a post and it worked well enough with one exception. I set the Facebook options up according to the Publicize Facebook notes and it sees all three Facebook entries but it won't publish to our profiles. It worked fine for the page however.
When it came to Scheduled posts however Publicize utterly failed. The post published to the site but none of the Publicize options went out. With MailChimp's Social this would happen on occasion and we had the option to republish the ones that failed. This option does not exist for Publicize.
