an open source software is never dead
selling a domain name is not enough to kill a free software

 also this namecoin.com domain have no value, no content, no namecoin related content or inbound links, people use http://namecoin.gw.gd , http://namecoin.info and http://dot-bit.org/

 also people already thought namecoin could be dead when there were threats of 51% attack , and merged mining came, and namecoin survived.
