I have recently wondered about this, should one use a hyphen in there domain name or no. I'm starting to think no (if the non-hyphen version is available), since it makes the domain a little more time consuming to enter.
Plus most people are so accustomed to just typing in the name as one word and adding dot com that this could cause people to not find your site right away. Then again it is kind of a trivial question, however I asked a few people before I recently registered another domain and they all said no hyphen.
So the question I pose to you is should one hyphen or should one not?
an example:
www.wickywicky.com
or
www.wicky-wicky.com
