Facebook might be eyeing the same crowd which is using Yammer or saleforce's chatter offering.I think if they start with a free tier like yammer and then go from there,lot of people might start using it as people are already familiar with Facebook.In my company i don't see people using yammer although it is heavily publicized. I think facebook has a better chance of becoming social network for work than yammer or chatter!
