It's weird you go through who is following you and you always find someone who's posts you see a lot but you're not all that interested in and then you find they stopped following you years ago and it's kinda liberating unfollowing them guilt free.
I sort of think there should be more of a mutual thing when following. Or at least an alert to tell you if someone is not following you when you are following them. I know you're supposed to follow people because they are so very interesting but, come on, most people aren't that, are they? But you follow and see their little takes on life and they see yours.
I personally remove people from following me when I unfollow them. I just think that's polite really.
And I could never bear to be one of those accounts that have a billion followers but they only follow 12 people. Yeaugh!
