Since Gov. Martin O'Malley declared that the state's health insurance exchange website was functional for most users, anecdotal reports have been mixed. Some people report continued problems with frozen screens and other glitches that have bedeviled the site; others say they were finally able to enroll with relative ease. The preliminary numbers of new enrollments, though, suggest some genuine improvement. Monday saw about 1,100 enrollments, nearly 50 percent more than the site's best day before the fixes went into place. Some of that is doubtless because, with a looming deadline to enroll in coverage that starts Jan. 1, those who have been shopping for policies have finally made their selections. But improvements to the website must also play a role.
