"The Social Connections app from REALTOR.com® is the Facebook app that brings the power of lead-generation to your Facebook Business page. It's free, sets up in seconds, and gets progressively more powerful as you plug in REALTOR.com® and Top Producer solutions."
It's an app that works with your facebook business fan page and can generate leads for you and is fun to work with.
If you use this app for facebook let me know what you think. I'll post an update later on to let you know what I think of it after I have time to figure it out.
