Hash URIs *do not* mean you put everything in one document, it simply means that you have one identifier for the doc and one for each thing described within it, whether you put 1, 10 or 100 things in the doc.

There, <http://example.com/about#alice> is the name for alice, and that is described along with a lot of other objects in the IR <http://example.com/about>.  As the authors there discuss it, this is better for 'small' sets of names, whereas "the slash URI pattern" as described there is better for larger ones.

The idea is to have smaller more manageable RDF documents on the web, IMHO targeted documents are more interesting than ones which talk about a million and one things. Again, I will try and draw an analogy here; at is stands, sites like the BBC, have one document per story, there is nothing stopping the BBC from having one page will all of its content on it, i.e. with each article having its own #fragment, but it is a lot neater to have a document per story.

Mmm, not at all. The point I was trying (and obviously failed) to make is, that if are not using #fragments because you feel that you will have a single document with way too many #fragments in it, you probably want to think about re-organising your data into more than document.
