Having a name or not having a name doesn't mean anything. There are always 
new names to be created, you just have to be creative. Look at the big 
sites - amazon.com, yahoo.com, altavista.com, thehun.net - none of these 
names mean anything and yet they have no problems simply because they 
managed to think further than "book.com".
What interests me more is why we even bother with second-level domains like 
.com.au or whatever - I'd much rather have domainname.au and do away with 
the whole .net.au, .asn.au crap.
