I wonder if it's just a Google Reader issue or RSS are fading out. I'm not a huge RSS user but I would be very concerned by RSS decline, it was one of the rare inter-operation standard that was very positive, easy, clean, and helped a lot programmers to put things together.
It's bugged me when I've seen people say that Twitter replaces RSS. In my eyes, RSS is for feeds where you actually care about each item and the decision whether or not to read it. Twitter is catered towards dipping in and out, with items constantly slipping through the net.
