>these dances felt more pure/fun.
Wouldn't a lot of the older vocaloid dances have been created by the actual nico nico dancers, or the artists, MMD makers, etc? As opposed to by professionals? Maybe that's part of why they feel purer. Of course, even before anime idols were at their current popularity there were lots of real idol group dances being covered (and ponponpon is the actual dance they do in performances afaik) so it's not like it was all independent stuff back then either. Also I might be completely talking out of my ass I can't tell.
