Indeed, the Dane deserves beer.

Yep, amazing how much grind a well-crafted XSLT can deal with. But
don't forget the HTTP Conditional GET stuff too - that's a grind too,
but well worth doing.

Heh, understandable. 
I've not seen any reliable surveys recently, but the % of ill-formed
XML is more than negligible. I've got a SAX-like soup parser that
could act as a preprocessor if that proves a problem in practice. (The
ill-formedness can be intermittent - characters of the wrong encoding
pasted into a blog (HTML) form - I manage it a couple of times a month

Mr.Google should sort you there. Most blogging tools seem to support
the Blogger API and the semi-incompatible Metaweblog API and some also
use proprietary extensions (Movable Type has loads of them), all based
on XML-RPC. Remarkably ugly stuff (see [1]), but fairly
straightforward to implement. Joe Gregorio's done some nice work on
RESTful alternatives, however now all eyes are on the Atom Protocol.
I'd be interested to hear what RDF-oriented posting kit there is
around, all that springs to mind is Annotea.
