I am thinking of buying a .co domain as a .com is not available for my company name. While the .co is cleaner and shorter many of us have gotten used to .com.

• Do users only remember the domain name and add the extension (com, net, co)?
• Can a .co domain give a user the perspection that it is .com domain as they could subconciously assume by seen co ->m ?

This could have a negative impact as just adding a m to domain.co would get users to the wrong site, and email to the wrong site...

Should I stick with the "standard" or are there statistics that say otherwise ?
