For some this is the long awaiting release of a commercial company specific style Domain whilst others are already complaining that it will encourage another wave of speculative Domain name buying. It is true that one .co Domain has been bought for £200,000 which seems a bit over the top but this is likely to be the exception and not the rule. For most companies their new .co Domain will cost them more like £25 to £50 per annum.
Of course it was the original intention to use Domain styles to distinguish Websites and the type of organisation they represented and so it is hoped that the .co Domain will be used increasingly by commercial companies as their first choice Domain, particularly by new companies.
Whatever the commentators say about this it seems worth registering a .co Domain for your own business.
