Morning. Is any one seeing a difference between using www and no sub domain? I'm wondering if it's an age thing, but are the youngsters dropping it? I've noted that facebook, ebay, youtbue all show www. in their search listing (in Google) but twitter has is simply twitter.com (no subdomain)

@Dave "are the youngsters dropping it" - in what way? ...For sites they develop? Or when typing domains in the browsers address bar?? Do you have any evidence that suggests a changing preference one way or the other?
