I knew from your username I'd like you, clicked on your profile and see your only post supports my new (as of two years ago) world view. :) So, you've got a new follower.
Just wanted to let you know, though, it is fairly easy to see who has muted you. The below site shows you a chart of people who followed, unfollowed, and muted you for each day. Below that is the list of people and the action they took, newest first. So I can load that page and then search for "muted" to find those who have muted me. Might be nicer if it was sortable, i.e., could show all "muters" in a single list, but at least this gives you the info.
