I signed up with the site for updates, but so far the e-mail "updates" have been more like spam. Blind repetition of stuff announced long ago (e.g. Oct 1 Open Enrollment, basic Exchange features, concept of "metal" Plan levels, etc.) Visited the site today & had on-line chat with 'em, but still no info on Exchange for my state (which is using Federal Exchange, FWIW). IIRC, timetable published this yr indicated companies participating & preliminary rates for states on Fed Exchanges would be available by July. Hard to budget for HI/deductibles/copays without knowing what your bills will be.
BTW- I noticed that HC.gov is holding a "Google Hangout" tomorrow on their YouTube channel- along with rep's from political group "Mom's Rising". They are clearly left-of-center, so political balance will Rush Limbaugh be on their next "Hangout"
