Not Gonna lie, i spent years on Web 2.0 and have never commented or not even replied - never felt like doing so Made my bad habit
You're not alone and unfortunately I can say that this is the trend. Drop a gm or good night line, get 50 likes, you like the ones others are dropping and that's all. You can see that kind of behavior on Hive to, but not for long as they get tired of it. From there, they either adapt or quit as that kind of thinking is not popular here.
Indeed it's the trend they want to start on hive but unfortunately as you said will en up adapting (Good for them) or quite (Good for hive).
