Regarding the post about the huge influx of Kpop groups, I feel like it causes Kpop to lag in talent. Nowadays, companies are more into debuting groups just for the sake of debuting groups and they don't really have much talent or spark rather than debuting a group who has refined their talents to a point where they make quality music and have quality lives performances. I hope you understand what I mean by this. It's just too much to have to learn everyone's names.
I totally agree with the first part, though to be honest, if I loved the group enough, learning names would be nothing to me, just like with groups like Suju, SNSD, or EXO (lol, SM sure likes their large groups eh?).
