On the news just a few minutes ago: three guys in California, over last weekend, put together a website to do what the multi-million dollar government one doesn't. You enter your zipcode, and the site lists for you what policies are available, and what they cost.
A couple of evenings later they added a section that lets you calculate what, if any, tax assistance you are eligible for.
You can't sign up through the site, but it does give you contact info for whatever insurance company's program you pick, and you can sign up through it.
The site is, I think, "Healthsherpa.com" or something quite like that. I didn't quite catch it.
Also on the news was the mention that in North Dakota, where 37,000 people have or will receive termination notices, so far 30 have signed up for Obamacare.
