In my mind tasks you are "following" are tasks you want to keep an eye on the progress of. When creating dashboards showing tasks you are following currently includes all tasks assigned to you plus additional tasks you are following. Since you cannot unfollow tasks assigned to you this makes a messy and unhelpful widget. There needs to be a place to keep an eye on tasks your coworker or subordinate is doing. Either the ability to have a premade widget of "Tasks I am following not assigned to me or the ability to unfollow tasks assigned to you would be really helpful.
It's like trying to follow yourself on twitter or instagram. It just makes no sense. You already know your own progress and whats assigned to you through your to do widgets.
