so i joined Facebook world's top networking site & also orkut.
surprise surprise as soon as i joined them i managed to connect with school friends i had been out of touch with for 10 years!!! :o
its great to have sites which can reconnect people up like that & also make people make new connections.
just a nota of caution would be the tons of applications that can be added to one's profile.
not only isnt ur information shared with 3rd party applications which the original site refuses to vouch for (read at your own risk) but it also makes loading of member pages that much slower.
the more apps a person has added, the slower their page loads!!!
facebook's different from orkut in the sense one's profile isnt public unlike orkut where if u dont take care much info is shared. facebook gives a sense of control unfortunately u tend to loose it unwittingly the moment you start adding apps...
