>>86269188I don't think any are "hidden gems". I do agree with the second part though.
It's not that Hololive is so good at finding people, it's that Hololive makes people good enough and gives them a large following. And for this, I'd like to point out Sana. She was undeniably the weakest link in her generation, had never really streamed before (or at least to the level where she was at), and never really gave it much effort. She still somehow has 413K followers on YT even after graduating over 2 years ago.
She absolutely got some tips / basic training from Hololive, was given the necessary support, and was then introduced to a large following. Sure some of the people they get are good, but these people were just 2views beforehand.
This isn't a weird or somehow unique event either when it comes to social media and new genres/markets. Hololive is just the modern zoomer Machinima. The best thing for everyone in the genre is if it dies, for as sad as that sounds. It's not a stretch to say that Hololive has made the Vtuber market a thing, and now it's that same agency that is causing the market to be constrained. This also isn't me saying this so that another corpo can take over, I want the exact opposite. Now that a market has been established fully, I want the indie scene to actually explode and fill niches. Of course this may cause innovation within the sector to decrease for a bit, but with time innovation as a whole within the genre will improve and more interesting things will happen.
So yeah. Tl;dr:
Hololive is just the big fish in the pond. They can just make even okay people into important people.
