I would prefer that all lounge calls are effectively eliminated as it makes the lounge sound like a train station during busy periods.
The only possible exception to this would be for delayed flights and other things which are out of the ordinary.
It works overseas and it can work here as well. If flights are running generally to time and the departure screens are kept up to date there is no need for lounge calls for flights...
Indeed. I recently traveled Delta domestically, and their app is fantastic. Up to date gate information, lounge info and amenities by terminal, bag tracking (checked, on plane, off plane, which carousel etc) and live boarding info. Shame about the rest of the experience, but hey, can't have everything!
