Facebook Invites

The other day when I check my mail, a friend of mine send me an FB message. So I check it out and actually that message is to tell me that I am invited to her wedding and she wants my contact. I mean FB is now a easier way than SMS to get your friends attention. I mean thats hopefully they will check their FB often. Even the other day when my friends and I so called plan for the PD trip, we use FB to send msg to everyone and from there most of them replied from FB. SO I DARE to say that FB is more popular than Friendster.
