I'm glad to find a like-minded person.
I unfollowed all my friends years ago. If I want to see them, I peek into events we have in common, groups or I go to their feed directly.
My feed is mostly content from pages I enjoy along groups and communities that cover topics which interest me. I have a handful of friends who post about technology or hobbies that are not blocked from my feed.
I have an older account that has a lot of friends in common with my main one but without the blocks. I find its feed to be very painful to use. Photos of people's food, people's pets, people sharing "inspirational" quotes on stock photos, a lot of selfies and people's children. It takes forever to find information about topics I actually enjoy reading about.
I would unfriend those people if it did not come with the social problem of them coming back disappointed asking why I am no longer friend with them. As if social network contacts were actually friends and as if unfriending someone on a social network meant you are no longer friend with them. I also enjoy being able to check up on them every now and them, which I could not do if I were not connected with them due the their privacy settings.
