I agree with this, though when I use the term "query", I really want it to mean something that *may* point to *something*, where "address" to me means something that always points to an object (a list of nodes is also an object). If I ask for record 36 in a database, I would call it an address, but if I ask whether any records contain "foo" I would call it a query. As David points out, perhaps this is a religious/philosophical issue...
