Of course previous additions to the list of TLD's have mostly gone over like so many lead balloons. You see .biz here and there, but how often do you see .info, .museum, .coop, .aero, or .name? These options are just too late to the game.
The only place I've encountered .info and .biz is in spam. I think they have a negative connection in web user's minds as a result of this. I've never enountered the others, with the exception of one techie's site that was a .name.
