That Stop-and-go Mass in Baltimore seems like a neat idea.  One wonders if they have any materials or stock scripts for it.

Hand missals for the Extraordinary Form often have commentary on (e.g.) why the Gloria is sung after the penitential rite, what is going on the offertory, why the priest emphasizes his own unworthiness, etc.  For the Ordinary Form these questions are neither suggested nor answered.  Learning at least some of it (from self-study and from extraordinarily good priests) helped me and a few other reverts and converts I know deepen our relationships with Christ.  The interactive stop-and-go might help more do the same.
