Booktube is a corner of youtube dedicated to people talking about books. I can't remember how I stumbled across it but it has been going for quite a few years now and I thought I was the last to know. It is lethal when it comes to book recommendations if you find someone with similar tastes. My favourite at the moment is Jean Bookishthoughts. She is a phd student from Edinburgh In Scotland and is pretty prolific.

Well, this might be the thing that gets me on YouTube. :P
