From the article:

Amazon Posts, meanwhile, is a foray into social marketing. Creators of Amazon Pages can use it to update their sites with new messages, and Amazon lets users cross-post those messages to Facebook pages as well. Think of it as a kind of HootSuite-lite, with the ability to schedule updates and cross-post messages in a couple of places. “You can enhance your words with an image or a product. And you can plan ahead, scheduling the release of a series of posts on successive days,” Amazon writes. For now, Posts looks like it is limited to Facebook and Amazon itself but given that Twitter is also included in the Pages social widgets, you could see this also getting added to the mix.
