Mhm. I wonder where these come from ;)
Till now I was just lurking around, so please be lenient toward
me if I missed something ...

Let me please try to clarify an issue that IMHO is important
in this discussion. One should not compare oranges with apples
when talking about what is 'in' and what is 'not in' (the SW).

In greater detail, w.r.t. 'lo-fi semantic content' (btw, who
the heck invented this one):

 + RSS/Atom are concrete formats
 + tags are a paradigm (or a concrete implementation, cf. [1])
 + microformats [2], eRDF [3], and RDFa [4] are ways to
   _deploy_ (RDF) metadata
 + GRDDL [5] is a way to 'uncover' the RDF in non-RDF formats

So I'd like to conclude that _all_ content, metadata, formats, etc.
are welcome on the SW. We are not, I repeat, we are _not_ in the
position to judge on what is a first-class citizen, and what is not.

Cheers,
	Michael

BTW: Richard - in your opinion - are relational DB systems
     lo-fi or hi-fi semantic content? ;)
