I just scooped up a bunch of domain names for the new .eu extension. I randomly read an article the day they were released to the public and because I'm a Scottish citizen, I was able to buy them. I picked up a lot of travel oriented domains, some football domains, mortgage domains, and of course
www.petsell.eu.
Who knows if they'll take off but the EU definitely believes in it and this isn't just another .to or .cc domain extension. This is as strong as a .co.uk in my opinion, if not stronger. So for $15 a piece, it's worth a shot. And who knows, maybe a new name will bring about a new idea/project.
