The website's easily among the best this government, or any government, has ever created. It hasn't had a single minute of downtime (the Healthcare.gov servers have handled the load without a hiccup), it looks great, it's easy to use, it's mostly open source (on GitHub no less), and during off-peak hours I had no problem making an account. All that in a few months with a small team and no headline-making budget over-run. The only "non-functioning" aspect is likely that the legacy systems it talks to can't handle that many millions of people a day. Even in the face of those failures, the site doesn't crash or unhelpfully throw you some cryptic error code, it puts you in a queue and eventually tells you it's too busy and asks you to use the call center in the meantime.

Sure, it's not accomplishing its goal for everyone yet (over 2.4 million have been able to sign up for new plans, or so I heard on NPR today). But, from the perspective of "I could've built a better website alone in my bedroom", no he couldn't, as what this team built is working great despite doing a lot more behind-the-scenes than one might expect.
