I think it is because of the extension. it is doing great around the world, but aparently isnt doing as good in the US. that of course is bound to change.
in the information age, .info IMO, will one day become a key player TLD (its already there globally).
I tried to sell GeorgeWBush.info on ebay (I was asking for a LOT more for initial bid and my reserve was high). And thats the US presindents full name!
Havent sold it yet, but then again, havent really marketed the domain very actively.
Will start doing so from Monday.
just keep relisting your domain on ebay, it is bound to catch some attention.
