I know that :-) (02)
Google up on: RDF invented Triple, you'll notice I debunk that
misconception repeatedly. I also never fail to highlight Lisp genealogy
re. Linked Data genealogy etc.. (03)

Yes, I actually know him, and had some dealings with him way back after
his Netscape stint. (05)

I said Linked Data which != RDF. (07)
My RDF reference was simply about the fact that to many, DBpedia dataset

it used some Semantic Web tech etc.. (08)

You mean, the Linked Data it ingested, of course that could be the case
if the data quality (with inference in mind) was low. (010)
