Well, from what I understand, this is a really limited method, because (a) it returns posts with some kind of quality filter enabled, meaning you aren’t guaranteed to get all responses to a tweet, and (b) with a free account I can only return the last seven days of content, which means anything retweeted (or something) that’s more than a week old is toast.
Am I correct in these assumptions?
Not only that, but the user mentions list only returns the last 20 mentions, which makes it useless for getting a complete list of responses for a given tweet.
This also won’t work for getting responses to a tweet from someone other than the logged-in user.
Is there seriously no straightforward way to retrieve the replies to a tweet? This seems ridiculously complicated for something that should be a core part of the public API surface.
The ability to view a tweet’s responses is pretty critical to any Twitter client.
