Looking For The Best Social Website Script

I have killer domain name for a social site I want you guys to list the best free social website scripts..Thanks

 

If your talking about a site like Digg, than Pligg seems popular. You can get it here:http://www.pligg.com/

If your looking for something more like Myspace there's PHPizabi free from here: http://www.phpizabi.net/?L=home.index

 

hey do u have a demo of Pligg somewhere or may screenshots. I am really interested. Thanks

 

You can see a bunch just by googling "powered by pligg" or from the My Pligg Site section of their message board.
