Hopefully, the new “opening” in RSS allows some experimentation in presentation. Facebook (and presumably Google Plus, etc.) are investing heavily in algorithms to decide what you’d like to see — but there is heavy suspicion that the ranking is influenced by payment of money. The overwhelming amount of stuff is overwhelming RSS’s usefulness; I have plenty of sites that have a four-star post once a month. I’d never see it in Google+, or twitter, or facebook. But I’m reluctant to have all of my content served up by Google — it’s killing the part of the web where you discover something you didn’t know you wanted.
