Do you own any .eu domains?
I nearly ordered a whole lot then stopped myself, as I did not know if they would become as valuable as .com's

.com will always be most popular, but .eu is still valid for sure. Still, I wouldnt use it unless its a site relating to europe, because .eu will just confuse people otherwise.

I dont own any myself, but if I ever make a site targetted to that part of the world, I would definitely register one.

But theres no rule saying you cant use eu as a non-euro domain right?
I see how it could get confusing for users though, but hey if the domain is cheap i dont see a problem going for it.

theres no rule that i know of. they could not police that anyway, especially if you sell off the domain to someone else.
