Here at Brightcove, we have been using ReactiveCocoa internally in our new iOS SDK. We expose some ReactiveCocoa to the consumers, but not a whole lot yet. Overall I love working with ReactiveCocoa. The guys at github run an open source project the way it was meant to be run and are extremely helpful. One downside is that it makes debugging memory leaks/crashes/retain cycles more difficult but that will be inherent in any block based API. It is still worth using it though.
