I think a math show without a way to "communityize" it wouldn't work as well as numberphile. Some creators often dislike the comment section because it's a breeding ground for trolls <b>*glances to the side*</b> , but many times people is more interested in the comments than the video itself. It's like going to the movies with a friend. It's not just about the movie, but about commenting it with your friend over a burger/drink after watching it. ^_^ (more or less)
