Facebook as a CRM Solution

Why?

Many businesses already advertise on Facebook and use marketing automation on Facebook. Why not extend this to a more complete CRM solution?

How?

One solution is to have facebook develop it, which would have better integration but would also be a much more closed system (no integration with external automation services.) Another would be a 3rd party solution using the Facebook API. In either case, Facebook would have to allow individually identified Facebook users to be “visible” to the CRM.
