I just re-discovered this page that Tim BL put up in 1999 -

Semantic Web - Why RDF is more than XML

It's actually pretty relevant here, even five years later.

BTW, I found this while working on on-the-fly clustering of bookmarks 
using just their titles.  All that semantic content in titles, and it's 
so hard to get at (if you are not a person)!  This title clustered 
nicely under "Semantic web".
