You are right, the majority of people go to an event because they have been told about it being popular, have heard of the DJ (haven't a clue what he plays), love the track they had in the charts, heard they have fantastic fireworks or want to go somewhere busy to pull. They aren't going because they like the music and then tend to wonder around the club or just stand.
I can find myself routed to the same spot in a club for hours on end, most people did in days gone by. It has just totally changed.
It is all fueled I believe by attracting the faux VIP culture, the majority being there for all the wrong reasons.
Looking forward to the day (which will be soon) where something new will come along to take their interest.
