what will be happen when there will be no domain available with meaningful name or 4 to 5 character name???
I think there are les then 3000 names in 4 letter available right now. 3 characters they are not even dropping out of aftermarket. 2 and 1 characters are non registerable. Even if you find one. Yeah more TLD's will be invented but I don't think that any TLD might overtake .com in future. It has became the base of the internet. No matter what kind of TLD's this people invent.
