California's done it, Kentucky's done it, Minnesota's done it, and even Massachusetts somehow manages to do it every day, for goodness' sake. Yet HealthCare.gov isn't doing it—at least not for now.

While the agency that oversees Obamacare is now promising monthly updates, some advocates want more frequent data disclosures.
