Social networking in Office? Its Not Professional.

Social networking is the talk of the day, they have replaced pubs where people used to hangout after office hours, now its all My space, Twitter or Facebook. If you are not in it then you are ancient. These social networking does give you kind of security from the prying eyes of the manager.
Social networking sites have also become great place to market or to recruit
Its true that networking sites have started providing more Source of hire to the recruiters...
Its become now that if you are not on Twitter, Face book, My space the chances of a recruiter finding you is very very very less. The world has come to this and will continue to grow on this.
But this is not the true picture...
How many companies actually have a Facebook account?
Answer: not many, Only a hand full.
How many companies allow access to social networking sites to their employee?
Answer: Only a few do.. (I am happy, my company does)

After all it makes less sense to hire from it if companies deny it.

My company has banned all such accounts, but that hasn't restricted me from using any of those. It is not necessary that one has to be active on networking sites only at work. This can be done from home, internet cafes, and in most of the companies there are separate computers provided for employees to check their personal e-mails or social networking accounts during break time. I also did not understand how does it matter whether company has it's facebook account or not?
Individuals create such accounts by choice and companies have nothing to do with it. It's personal and not professional. Though recruiters have their professional interest as they get many candidates eg. you can get young professionals and talents on facebook.
