While we don't have to worry so much about "megachurches" (though Three Cranes is rather large, clocking in at around 50 people who are somehow officially related to the Grove, either as Members or as Friends), the social media aspect is huge with us: demands to be on e-lists, video chats, Facebook, and other net-savvy functions are high. . . so high, in fact, that those who are visible and quick to respond are seen as better at "doing our jobs" than those who aren't, which is a troubling (if understandable) trend. The social aspect of being a priest can really, really wear on folks.
I like the solutions hinted at in the article: yearly retreats (with longer sabbaticals every few years), teaching Priests to say "no" (I've learned that one, for the most part, pretty well), encouraging discipline of any sort (particularly silence, meditation, prayer, vacation days, etc.), and calming the need-for-growth mentality.
Anyway, food for thought.
