I hope it works and wish for the best. Escaping the Walled
   Garden of Facebook is tricky business. You may need to keep a
   strong presence on FB as, "People go where the people are." An
   interface (app) keeping the connection open would be good.

   Breaking free is tricky but possible. The most enormous of
   efforts can get you a 1% interest and a 0.1% dedication, which
   should be enough to sustain your project as it grows.

   Also, utilize existing systems. Think of it as "sinking your
   spider legs" in. One spider leg stays in FB, another spider leg
   on youtube, another spiderleg on google+... and have a spider
   leg in as many existing social networks as possible.

   This will support the body of your website.
