Zoom is just too convenient.
People are busy and stressed out. With Zoom, no "getting ready" for the meeting (except the real diehards who do), and no commute to the Hall and back home (and with Halls having been sold everywhere, many are traveling 10-20 miles in our rural areas).
PLUS, you really do not have to sit there and listen!!! Turn the camera off, mute the mic and open a beer and watch TV.
Elders & MS are getting "orders" to show up in person. They in turn, "encourage" anyone wanting to make points to get appointed to show up in person. Then, there are the lonely people that will show up because it is their social network.
