I have a great domain its City.travel im not sure what i should do with it. I was thinking maybe a trip review kind of thing but how many of those are there. Can you help me if I really like your idea i might send a little bit of money your way.
try and sell it to a travel company and cash in on some good money or you could develop a map of the world and on the homepage where people can click on a certain area and find info about certain cities, you could also allow people to post their images of that certain city and their comments and experiences.
you can give people an option to build websites under these subdomains - for free or paid... you can even offer them some webspace... or you can offer redirection for travel websites.... possibilities are endless
