The opening up of the .co domain extension yesterday has prompted many blog postings and comments, and posts in domain forums. From what I've seen, quite a few people have regged one or a handful of .co's that are good quality keywords to them, or words that have special meanings to them (first name, existing business, familiar location, etc.). There also doesn't seem to be as many people bashing .co as were bashing .mobi and .me when they launched.
The best points about .co (to me) are that it has a known meaning of 'company', it is short, and it looks close to a .com. Yes, it is still a country code extension, but like .tv .me or .nu (to the Swedish), it has marketing features that some may be able to use. There is also the potential for traffic from web users forgetting the 'm' when typing in .com, however as long as you are not infringing on trademark terms it is just an extra benefit.
There were a few high profile .co sales prior to the general opening yesterday, where are they now?
E.co - domain still forwards to the auction page
O.co - domain forwards to Overstock.com, but if you check O.biz it has it's own webpage, which might be in the works for O.co
T.co - Twitter url shortener, if you go to the page it has a short write-up. I don't know how long it's been up, but it must be fairly new. The page says:
Twitter uses the t.co domain as part of a service to protect users from harmful activity, to provide value for the developer ecosystem, and as a quality signal for surfacing relevant, interesting tweets.
If you click on 'Learn more' it continues to say: Twitter’s link service at http://t.co is used to better protect users from malicious sites that engage in spreading malware, phishing attacks, and other harmful activity. A link converted by Twitter’s link service is checked against a list of potentially dangerous sites. When there’s a match, users can be warned before they continue. Our link service will also be used to measure information like how many times a link has been clicked. Eventually, this information will become an important quality signal for our Resonance algorithm—the way we determine if a Tweet is relevant and interesting.
To end off, yes I did pick up a few .co for myself. I wanted to get Nelson.co (BC city name) or my first name (or a first name of someone in my family), but all those were taken early on. I did manage to get these in .co
Voyance (french word for fortune telling, a big online market)
Maquillage (french word for makeup)
Revelstoke (town in BC Canada that is building a massive ski resort)
NAA (a good acronym and I also own the .mobi)
That's it, for now I am done with .co unless something else comes to mind.
What .co did you get?
