I think same as You regarding Microformats, so implementing on the
same page a lot of microformats can be generate more confusion and
disorder also on code-reading (I don't know for machines, but Yes for

Of course, I've just printed [7] and looking for an implementation.
Well, I've also tested grokFOAF but one of limitation (connected with
simple implemetation) is the absence of combining seeAlso to link
simply other FOAF (one of the most important features of this)

Yes, I've also talked with Pasquale Popolizio of websemantico.org (he
initiate me to the Semantic Side of Web) and we agree that in future
RDFa will be the best way.
