Here's the results so far in True Blue Maryland:
Maryland had 174k unique web site visitors, 13,532 accounts created, 566 applications submitted –> 326 enrolled.
.2% of hits enrolled. 2.4% of those creating accounts enrolled. I suspect that the other 12,966 people saw their rates and went "I thought this was FREE!!!" and did not even apply. It just gets better and better.
Had they signed up millions (or even thousands) they would have been all over the news harping about the success of Obamacare. But given that the numbers a infinitesimally small, they are parroting "Well, there's lots of interest." They may be interested but it would not appear to be bringing in the numbers it needs to.
