Thank you for helping me on... the only point I don't get is:

So while I thought <http://oskar.twoday.net/> shouldnt be used to refer
to the Blog as "the collection of posts", you seem to say now that the
HTML-document returned by the server might well be taken as a suitable
representation of it. Therefore (if I understand you correctly),
<http://oskar.twoday.net/> *can* be used in RDF to refer to the thing
known as "Oskars Blog" in the real world.

Now isnt this a direct contradiction to the starting point, when TBL
wrote:

Identifiying a document is not the same as identifying a blog, even if
the document is part of the blog. I can make statements about this one
document that are not true for the blog and vice versa.

Whats the point I'm missing? Or am I being fussy here again? ;)

Thx
Oskar
