HealthCare.gov got steady consumer interest and also hit a bump Monday, the first weekday of the new sign-up season under the president's health overhaul. Consumers trying to open their existing accounts on the website got this message off and on during the afternoon: "HealthCare.gov has a lot of visitors right now! We need you to wait here, so we can make sure there's enough room for you to have a good experience on our site." At other times, this message was displayed: "We're busy making HealthCare.gov even better! Sorry you can't get what you need right now. Please come back and visit again later."
