Netizens need to learn to behave with responsibility. In real world, it is ok to be casusal but on the net, people think and do things. What they forget is, for every link clicked, they are unassumingly saying, "I agree". On the net, privacy is as important as is freedom. as for orkut, the only trouble is they hav discontinued the 'by invitation only' system making it unsafe and less personal. but then, orkut is just a fad in the history of internet, n shud be taken as just that.
