The Page Flurry application allows you to control your Facebook, Twitter and other social media activity from one easy to use desktop app. Keep track of your activity, and avoid being flagged by Facebook for bad posting behavior.
This application can also be used for other blog sites. See the full set of 'how it works' videos at: pageflurry.wordpress.com
This application is one of a kind and serves a purpose that no other Facebook app can, so it really has no direct competitors. This application helps people do page posting and commenting more efficiently.
