Just got a report from one of my users that a message he posted through our app made it through to his Twitter timeline twice. Looking at our server logs, I can see that when he posted, we got a timeout from Twitter and successfully tried to repost. My guess is that the timed-out post actually went through, as did our report.
We don't want to be hitting Twitter with duplicate posts, which is why we're careful about when we retry. However, I've seen references to Twitter filtering out duplicates, so I was under the impression that Twitter would detect and reject the repost message in this case.
