Of course, one would have to learn to draw the line to see how the Facebook At Work service will allow folks or users to separate their work identities from their personal Facebook persona. Perhaps Facebook might want to take a leaf out of Google Apps’ page in this particular matter, where logging in with your company’s Google Apps account would be managed by an IT administrator, where it is fundamentally different from the one which you use when it comes to your personal Gmail as well as apps, albeit there is the option to link both of them and sign into multiple accounts simultaneously.
One more thing – will Facebook rely on ads in Facebook at Work? Only time will tell. Since Facebook is testing it internally, one can only come to a conclusion that Facebook for Work has approximately 8,000 users on it already.
