The day i saw my friends and even my daughter & SIL daughter spending endless hours on FB i did noteven open a account, though as Mr.Krish says the tools are good but people tend to use them for ulterior motives. I am happy with TB and few other sites... No FB, though daily we get invitation.. i just delete them....
Cheers!!
People become wise after the event.
You are Wise even before the event!!!
