Google's step into Semantic Web - genuine move or a dodge to avoid criticism?

About two months ago Google started to promote two Semantic Web techniques, RDFa and Microformats. We were delighted - finally, with Google doing so, we saw the efforts of all previous trailblazers coming to the fruition. We believed that the first, indeed small step Google did, would be a real leap into the direction of Web 3.0 or, as I used to call it, "Web full of Meaning". Maybe it is still to soon to see the fruits, but we should already see some buds. We don't.

After some reflection and a scrutiny applied to Google's "Rich Snippets" page, or "Structured Data Page" where they announced the support, one can really be disappointed. The simple, I would say - primitive ontology they used (their own data-vocabulary.org) is very strange for its mean scope of concepts. The decision to allow first only for semantic descriptions of reviews is strange and forces us to ask the question: What the heck they are doing?

It seems they did not notice the role of such respected yet also simple, ontologies like Dublin Core Metadata, or when it comes to people - Foaf....

Ian Davis in his post, calls it straight: Google’s RDFa a Damp Squib :-)
I support Ian fully. I try to be far from conspiracy theories, but the way Google steeped into the arena of SW, seems to be more to postpone its advance, than to promote it....

So disappointing ...
