Hi5 is the worst now....all the lame stuff are done on that now, like forwarding junk messages, adding people for the sake of adding to the friends list to show they hav lot of friends, putting all fancy, glitter stuff to decorate the profile like a Thorana.........
Facebook is THE BEST 'coz its classy....simple as that....
Well Elakiri is very different to both FB and Hi5 coz 99% of people dont maintain true identities so can't get an idea at all to whom you are messaging to...
