Im receiving type in traffic to footballtickets.co... so your wrong - Im yet to really do anything with it though
I just get the feeling that .co will be similar to .mobi, lot's of hype and interest by domainers who will buy & sell for months until they realize that the general public are not interested & then prices will tumble. But hey, get on the bandwagon now, hype it up and sell when you think the time is right and then get the heck out of the market before it get's shakey. Play it like the stock market and you could make a fortune, play the market wrong and you could pay heavily.
Many people that are not in-tuned with the net may not notice your site or may be wary; however, as mentioned before it is a growing market and could be a good investment if you market it right.
