taking facebook out of love

It's become so common that a guy asks if a girl is on facebook rather than asking for her phone number.  I mean don't get me wrong I'm all up for new forms of communication but this could become a tragedy.  With a click that initial interest can dissipate as you go through photos and comments that leave you questioning if that was the same person you met the other night. Furthermore, unless you are sending msgs back and forth, the communication doesn't have much room to evolve. Plus I thought that was what msn was for.  So I have decided to block all my photos and wall to individuals who insist on making a fb connection.  Maybe this will get them off the couch and force them to dial a number and if they don't, maybe that's a good sign.
