This was incredibly helpful, thank you! I’ve been reading up on RxJava a lot lately since Square mentioned this as a replacement for Otto when they deprecated it, and it seems like an awesome library. While I had somewhat of a grasp on RxJava going into this article, had this been the first one I read it would have been way more useful than where I did start. Also, including various Activities to emphasize your points and then linking directly to them is a super helpful writing trick. Overall great work; the article was clear and to the point.
