I do not agree with your question. I think we should not compare our educational website with those social network website. And the point is we are in very new stage. Even all the orkut and facebook are quit old. Once we reach in that stage then we can compare with them. For that we need to work hard and we need to cope our webmaster.
People here should not focus for their point or to be in top and do not be money oriented. This is not a Financial site also.
You people more focus how can you deliver more to the customer to be more userfriendly.
