Dead & undead are not really interesting categories. Who is using RSS? How are they using it? What depends on or is enabled by RSS? What are the feedback loops, and what are the trends? There is difference between podcasts, news sites publishing a headline-only, twitter-like feed and a blog publishing full text essays. The protocol itself is a protocol. The interaction between consumer, publisher and protocol is what's interesting. That's a very wide field of possibilities. Fwiw, in the context of a FB alternative, id be looking out for trends that blur the lines between consumer and publisher. Its certainly not sufficient, but I imagine that any open (or not) alternative to social networks will have this quality.
