The only complaint about Twitter I remember that hasn't already been addressed here is the capability of editable 'toots.' Is that a possibility? That won't happen. There's actually a good reason why they don't do that. It's simply because you could make a toot about one thing, have people favorite it and share it, link it from other places, and then suddenly, it says 'Heil Hitler,' or something.
