Obamacare website HealthCare.gov got off to a rocky start last October, when a rush of would-be customers crashed the insurance portal, making it nearly impossible for anyone to sign up for coverage online during the first few months of open enrollment under the president's health care law. The experience was painful but instructive, and officials are hoping to avoid another mess this year during the second open enrollment period, which begins November 15 and lasts for three months. They've streamlined the application process, according to the Associated Press, by reducing the number of pages consumers have to click through from 76 to 16. They've also optimized the site for browsing on mobile devices.
