This question didn't get any traction in the domain thread so I am reposing it in the SEO one.
Now that some of you have had your .co domains for a while, would you be willing to share any insights as to their SEO performance from a US based audience perspective.
My understanding is that Google Webmaster Tools allows regional control of the domain to allow it to be a US or global site, vs just the ".co"'s original intended geography.
What success have you had in using keyword rich .co domains in your SEO results? I would be very keen to hear feedback as we are in the process of launching a new online service that would utilize such a domain.
