.co.uk first, now .co domains. Niche ideas?

As you may know, from 20th of July .co domains (Republic of Colombia)
is for sale, with 11 different registrars, one of it being Godaddy. "& Co."
is already used in names of many long ago established firms. Have you
registered any .co's? - any ideas about practical value of these names?

No, I have not registered them but all new extensions take time to get noticed by google so better not go for them.

.co domain is easy to remember and very unique as well :)

.co is easy but dont you think it represent a country so it can be difficult for the global world
