Say I want to make a correction to a tweet, if there's a typo or something. If I delete the old tweet, what happens when people have already seen it and/or replied to it?
Will most Twitter clients figure out that the tweet was deleted, or will two tweets (the typoed and the corrected) show up in the clients? What about on the website? What about in someone's mentions list? What happens if it's in the middle of a conversation chain?
If you click "reply" on a deleted tweet, either on the website or the client, what happens?
Basically, is it bad netiquette to delete a tweet, because most consumers expect them to be permanent? A lot of the bigger accounts I follow do corrections manually via a followup "oops, I meant X not Y" tweet, maybe for a reason. Or is this perfectly OK?
