FOGT (Facebook OpenGraph Tag Generator) is a Mac OS X app that will enable you to add the necessary metatags to your blog posts for seamless and controlled integration into facebook.com.
Just design how you want your abstract to appear on facebook.com, generate the code and copy and paste the code snippet in-between the open/close "head" tags of your webpage.
NOTE: FOGT can only be purchased via the Mac App Store (the buy link redirects you to its App Store page). To purchase/download applications via the App Store an Apple account is required.
