I like it so much that I may read the FaceBook api and write something myself or find another plugin that does the same sort of thing, but I just could not get it to connect to an app I made. I gave it an hour, and I still get Add Link to Facebook needs authorization, and the link in that error takes you to the page you are already on.
The directions were spotty, poorly written and did not match up with the current features on Facebook. Not that we can blame the authors. FB changes everything all of the time.
