That is an error.  You cannot use the same URI to identify yourself  
and your home page.
The moment a server returns 200 OK for a request to the URI, it is  
saying it identifys a document.
You can't use the same URI for yourself.
You could use http://www.example.com/mophor#me as a URI for yourself or
http://www.example.com/mophor/foaf#morphor orhttp://www.example.com/ 
mophor/me and have a 303 redirect from their to a document about you.
