Experience with Social & business N/w sites.

I have tried quite a few sites to claim to know somethin about the social sites by now. I have tried orkut.com, linkedin.com, rec-all.com, ryze.com, nitalumni.com etc.

On thursay/friday something unexpected happened. A fellow school mate whom I have not spoken since school days (ok, I talked once after coming out of college), contacted me. I gave in and accepted her invitation. And voila, people I thought I would never talk to in life again suddenly got in touch :).
