Attention spans have shrunk. And not just with younger generations. I can agree that the waits for MU*ing is more than most young people want to deal with. Its barely anything I want to deal with. A lot of time you wait for someone else to pose and they crap out some rushed line because like the younger people their attention had been elsewhere and a 20 minute wait was spent with 19 minutes of it focused elsewhere and 1 minute to bang out a pose. Its a chore to get people to pay attention during a combat scene to what's going on. As though other people's turns have nothing to do with them. Then when their turn comes up they take 10 minutes to decide what to do as though they haven't had more than enough time to decide already.
Add in the drama and the negativity and all the other stuff we gripe about and can anyone really wonder about it? In fact I'm surprised there is as much activity as exists right now.
I would love for more people to be into the hobby, but I'd prefer if the few people who are into the hobby were of a higher quality. I think if we had the latter, we'd get more of the former.
