This could be just me, but I noticed that when I edit my posts it's no
longer showing that I edited them.
Even given our requests to reduce extraneous visual clutter, I think this
is a useful feature. Especially because people can essentially delete
the content of their posts within discussions, making it really hard to
follow the thread of the discussion. If you can see that the post was
edited, you can at least say, "Oh. There used to be something here."
