DreamHost gives me the option to use
www for my site's URL, to remove
www from the site's URL (i.e., "naked domain"), or let the visitor decide. Is there a best practice for this?
I notice Google treats the naked domain vs
www as separate sites (they are both registered in Google Webmaster Tools). I would prefer they are treated as one unified site by allowing Dreamhost to do a moved permanently redirect on one or the other.
What research is available that shows one style is more comfortable to users than the other?
