Since there seems to be some doubt about the ability of people to successfully enroll for health insurance on the healthcare.gov web site, I went through the enrollment process this morning (about 7:30am EST) and managed to enroll without a hitch. I'm in Ohio, where the Republican government has refused to set up a state exchange, so this is through the national exchange.
Screen shots of the process are shown sequentially below. I had previously set up an account last week, so these screen shots just show the enrollment process. Click on any image to see a larger version.
