I like the betterdoctor price maps! Too bad you didn't have a chance to enter our competition, because you might have been a winner. By point:

1.) Good choice 2.) You need to consider co-pays as well as allowable charges, deductibles, co-insurance (if applicable), and benefit maximums. 2b.) The quality data out there sucks (hard to measure quality in HC) and is hard to find. 3.) Cool 4.) Ibid 5.) Clever

HC now is like the internet in the early 90s. Huge opportunities that will hopefully attract talented developers, technologists, and entrepreneurs.
