>>68304654nah i think its mostly because hololive isnt the only game in town anymore, so everyone split off into their own little threads. people's attentions are split every which way, according to company and specific chuubas, and only rarely do they congregate into one place again, such as in happenings like this one.
im sure anons would like (You) to know about what their oshi did on this particular stream, and maybe theyll make OC if theyre creative enough but theres no motivation if the rest of the board will just post "who?"
pic related, everyone knows who this is, but i doubt everyone will know the particular layers of injokes and chumbud culture that led to this being made, making it literally unreadable for everyone else to appreciate
also, major ones like /hlgg/ literally still have their own OC (like the guy who makes the comics)
