"If you have a Page on Facebook, you'd probably like to know how many people interacted with the stories you've posted. Now, Facebook is gradually rolling out Post Insights, a new feature that lets you see the number of impressions and feedback for each post. \nWe're not seeing post insights on our posts just yet, but from what we've read over at All Facebook, it's a very simple feature; besides the number of impressions, the feedback (shown as percentage) lets you know how many visitors actually interacted (for example, liked it or commented on it) with a particular post. We'd like to see a more detailed analysis of our posts' visitors, but post insights are definitely better than nothing. \n\n\n\n\n[image courtesy of All Facebook]"^^<http://www.w3.org/2001/XMLSchema#string>
