.me is a fantastic extension and its an actual tld because montenegro allowed it to be so. - check out this one The Sh**
its a great extension to make fun blogs and sites like there were at the dawn of the net, theres still alot of them available so people should get on one and make a fun site before they legitimately take off!
facebook recently registered fb.me. The quickest way to get to facebook now is by typing fb.me into your browser.
.me is one of the best made extensions next to .com in my opinion, it has alot of potential in terms of being a tld and being brandable/ memorable.
