I'm in general with Chris. Of course RDFa is/can be used to do Linked Data.
But rather than wasting our time in ranting how bad the world is, how about
just making it a better place?

1. Clearly, we need to motivate why interlinking is  beneficial or at least
offer 3rd party services that do the job for the publishers (if they don't
see the benefit or have other priorities).

2. Again, rather than discussing endlessly about what is fair and what is
not and who should be there and who not and so on ... hey, it's the Web. An
open, free ecosystem where you can just put up your own visualisation,
diagram, stats, etc. - tthe community will then decide how valuable and
useful it is.

/me back to work now; trying to help solve the issues rather than talking
about it in the first place ;)

Correcting one factual error in Gio's post, though:

> retailers so they're left out?
