Indeed - the server doesn't see the fragment.

Not at all.

Is the web of documents crippled because the server can't distinguish  
between requests for http://example.com/document.html and http:// 
example.com/document.html#part2 ? Of course it isn't - the server  
doesn't need to distinguish between them - it serves up the same web  
page either way and lets the user agent distinguish.

Hash URIs are very valuable in linked data, precisely *because* they  
can't be directly requested from a server - they allow us to bypass  
the whole HTTP 303 issue.
