PostRank, a social media analytics service we use every day here at ReadWriteWeb, will announce today a new Facebook application that automates the publishing of your content onto Facebook and captures reader engagement statistics to incorporate into analytics for your content across the rest of the social media world.

PostRank keeps track of how content gets passed around on sites like Twitter, Delicious, Digg, Reddit and many more. The service's ability to track reader sharing and discussion on Facebook has been hampered, however, by Facebook's being closed off to outside data collection. This new solution, a Facebook app that publishers authenticate with, is a smart way to make progress towards solving that problem.
