I own JonHall.org and JGH.biz and wonder why every time that I renew them. There is plenty of vanity out there though and the .ME registry is the master of marketing.
It will be interesting to see if .ME has staying power or not. It might but I don't think it will at the inflated prices that have been paid for some names. CoolStuff.ME is my only .ME name and it will likely stay that way unless someone wants to buy it, of course! I own lots .US, .BIZ, and .INFO. I have done OK on them. For the most part though a decent .COM names is worth several 'good' new extension names. Few peoples (potential customers or domainers) 'dream' names end in anything but .COM.
