The difference that I can see between deleting and editing is that editing a post, even to the point of removing all of its content, leaves a placeholder to show that something was there. This makes it more likely that subsequent posts that refer to it will make a little sense or be slightly less dis-jointed than would be the case if there was nothing where the post used to be.One thing that gets me:
Why can we edit posts (albeit within an arbitrarily short time frame), but not delete?
The last explanation I heard was that deleting posts "interferes with the narrative," which I find to be a BS excuse. If we're not allowed to delete, then we shouldn't be allowed to edit.
(I am not advocating for removing the ability to edit.)
It feels like a few designers had a concept meeting and we're the guinea pigs of its outcome.
Oh, and pay no attention to the man behind the curtain.
