I think you are missing the idea...that most users on the internet don't actually know much about domains. So many people actually type dashes. How do you think parked sites get traffic? A lot of people don't understand how to use a search engine. I know so many people that if they are looking for something...they just type it in a web address. For example... "chinese food". They will type chinesefood.com ...in order to find places.
