I also am not on fire about this API... Since our app, www.tweettronics.com, tracks user's twitter activities, I think that while retweeting has been popular it's mainly been a tool for spammage as part of user's desire for self-promotion and less as a tool for user attibution. Still the users have taken it up... it's just that what I'm seeing is that it's primiarily used to generate tweets and thus attention to one's account... On the other hand, it at least formalizes what is going on, making it easier to track retweeting behavior, to the extent that such tracking has any fundamental value as far as estimating user influence, given the signal to noise ratio that is going on.... I do think that this API can help solve other issues, such as the challenge of having threaded tweets. Is support of threaded tweets an intended effect of the api?
