The term ‘audience engagement’ is firmly in the ascendant now, complete with sub-terms: audiences can be engaged, less engaged, or unengaged. I think that’s it: just the three options. I’m slavishly following the zeitgeist, and use ‘engaged’ an awful lot, but I think I might hold out against unengaged. Will it be used like ‘unemployed’?

And also - is it engaged as in “engage warp speed Mr Spock”? Or engaged to be married? Or is it the opposite of Vacant?
