>Unlike Twitter and the other social networks, RSS never tried to capture the social graph, likes, comments, annotations, retweets, and etc of its userbase. It limited itself to posted content (mostly blog posts) and that was a missed opportunity.

Maybe it's just me, but RSS being all about content is the best thing about it.
This is the two competing goals of every publishing mechanism - one person wants to broadcast their data and another wants to consume it, and it's very rare for both parties to want exactly the same thing.
Except where the same person is both publisher and consumer. I run a couple of systems at work were RSS is invaluable, a website with news and a set of screens on the premises running Xibo, that ingest the news via RSS to display.
