Yes, it's interesting.

This has been known and ocassionally touted for AGES. I've attempted to start a couple of such projects and have been following the progress of other projects with similar ideas.

There has been near ZERO interest for them, because there's no currently viable business case for such projects, except "let the government pay for it." Data mining isn't THAT useful if there's no data in there - who would force entities like companies, universities or the SEC to push the data into the blockchain?

I'd be very happy if could find funding for https://github.com/WOTvision/wot1 and I can see a business case for it as a potential platform for legal, paid distribution of news between creators/reporters and distributors like news portals. But even so, no takers.
