Everything I know about vlogging (what to shoot, how to construct my video, where to add text or sounds) I've learned by watching other vloggers. I always had a preference for people vlogging about their lives in other countries (Canadians living in Japan, Americans living in the UK, etc) and that is what inspired me to go aborad and start vlogging myself! I even learned how to do the lighting in sit-down-talk videos by watching vloggers talk about their set up. So next to the fact I greatly enjoy their videos, I'm also constantly learning from them.
That said, I also follow a lot of animation and art channels, since I just love the format (and wish I could do that myself).
