How Do You See the Edit History of a Steemit Post?

I noticed that we are allowed to edit our posts. Since this is on a blockchain, is there a way to see how a post has been edited over time? Facebook allows this by clicked the "Edited" link, which shows all previous versions of a post. Currently, there is no way to delete posts, but if there is a way to edit, it seems almost as good as deleting, as you could just delete all the text in the post leaving an empty post. Correct? Edited
