Quite the opposite. The benefit is getting Facebook's algorithm, instead of a reverse chronology. I never found any of the million apps that tried to accomplish this to actually mix the news better than fb.

I liked the idea of prismatic, but it surfaced mostly clickbait. Feedlys popular didn't feel as dynamic. Have you tried using Fb this way, or are you just telling me I should use something else? Why do you think I would find rss to be an improvement (I migrated from rss to Fb lists.)
