Right now, the way to unfollow a post is to go to My account -> My follows -> look for the post through the whole list (there isn't even a filter/search) -> select it -> Unfollow. This isn't intuitive at all. I had to search the community to find answers to people who had wondered about the same thing before me.
Good UI is in the context of its object. Just like I can sign up to follow a post when I reply to it, I should also be able to easily change my mind. There should be an option on the post itself to unfollow, without needing to find a list somewhere else. And it's a trivial addition - a single button on the post page (the code to unfollow obviously already exists). Thanks in advance!
