Came here to plug this.

I'm working with the author to make a feed summary page like some other readers have, if you prefer to see things collapsed that way.

I don't use swiper, but Emacs + Elfeed is indeed a great experience; especially so if you tag all your RSS feeds when adding them. Also, if you have EMMS, you can play podcasts right away pressing P in the * elfeed-show * buffer.
