But that doesn't mean you should stop reading. Instead, jump in and participate! Leave a comment below about your favorite aspect of the show so far. What's the most interesting thing you've learned? Your ideas shape our future coverage, so comment early and comment often! And don't forget to join us again in June for coverage of SIIM (beginning June 4) and RBMA (beginning June 7).
