it's the content that's important
It's the content of your site that keeps me coming back for more ... the URL that I have to type is of no consequence.
However, if you are rationalizing all the URL's and servers, might I suggest (as a Canadian reader) as a compromise the "www.theregister.ca" URL that I currently use.
Change the URL all you want, but keep the content the same!
