Are there any plans to add an API call to return all posts that are in_reply_to a specific post? I'm constantly coming across tweets that are questions directed at specific users and I have no easy way of finding whether that user responded or not short of searching their timeline around the approximate time.
We could make great use of this on Tweetree if it were implemented. Thanks! John Fredrickson Draconis Software http://twitter.com/jfredson
