@pratik The idea that these emotions or affections be captured as verbs in the software, that is near the lowest end of the attention spectrum, in my book anyway. It is not engagement at all.
Ignore, gesture, comment, discuss; only then do you get close to engagement. But simpleton greedheads would rather have something to count.
Actual engagement requires prolonged focused attention, difficult in any circumstances, but near impossible for many wandering around the information circus.
