How much is the domain Social.com worth? We are about to find out. The domain will be auctioned off on June 8 at DOMAINfest Barcelona with an opening bid of $5 million, according to Moniker. Moniker and SnapNames will be jointly selling the domain on behalf of Scott Carter , the original owner who first registered the domain back in January, 1995. Back then, he had to pay $100 a year to Network Solutions and all the paperwork had to go through the mail. Depending on how high the bidding goes, Social.com could very well end up being one of the most expensive domain sales of all time. The current record-holder is Sex.com, which sold for $13 million in April. Bidding for Sex.com started at $1 million . And Social.com is arguably sexier right now.
