I'm not a big, big foot person myself, but I can take them in small doses. That said, I sometimes find myself disappointed with the majority of the content being majorly oriented towards feet, if not completely oriented towards feet. The thing is, personal tastes always fall beneath what the majority want. A lot of people are into feet, so clips focus on them in order to make a profit, stories and artwork focus on them because that's what more people want to see and what the majority of authors/artists care about, etc. etc.
Think of it if the same question was asked about movies. "Why is everybody so enamored with superheroes? Trust me, there are other genres to focus on and other plots movies could have. Superheroes never did anything for me, yet Hollywood is 99% superheroes, I don't get it, sorry."
Why superheroes? It's because that's what the majority want to see. So while you may want to see more westerns or romantic comedies, Hollywood's going to keep churning out superheroes. That's the big thing of the moment, and that's what's selling tickets. The same is true of feet. The majority wants feet, so those of us who aren't so into it are stuck dealing with it, whether we appreciate feet as much as the rest or not.
