OK for those of you desperate to take a look at Revolution Health’s "invite only" site, here is an officially blessed invitation to go sign-up  (and of course to look at what $500m buys you!).

Meanwhile, at the other end of the opulence scale, start-up Medbillmanager is attempting to compete with Revolution/Intuit et al in the way consumers deal with their medical and insurance  billing/payment.

Obviously it’s early days. But it’s well worth taking a look at both of these two sites to see how new web technologies are putting information, organizational capability, and just maybe power, into the hands of consumers.
