Heck yeah! I watch a bunch of the Hololive girls. Though usually only in clips and shorts due to time constraints. Recently Neuro clips have been really fun too.
I think watching virtual youtubers just like subscribing a idol who can sing, dance, paint and live. Its a not-too-bad way to learn Japanese and know Japan more. btw, I subscribed only one vtb, Nakiri Ayame, from hololive.
I normally just watch some clips popping out of youtube. And sometimes I just browse the /vt section and read some of the gawr gura thread, fauna thread, and sometimes Shiori thread.
