Actually Vick!... the www is the subdomain of a domain and yea it does get picked up a bit differently however the example above was as follows:
"does google see the link back
http://www.mypornsite.com as a differnent site if linked to via
http://www.MyPornSite.com or for that matter HTTP://WWW.MYPORNSITE.COM?"
The above question had only one domain and that was:
http://www.mypornsite.com
not
http://mypornsite.com
.
