Although I haven't really felt any remarkable improvement on clickbaiting (still a lot of "20 letters from children to their fathers - no 19 will break your heart"), Facebook does not stop to try and figure out how to make your newsfeed more relevant. Now it's about promotional content by fanpages that makes organic posts in newsfeed feel too promotional, and Facebook says this comes from feedback during the frequent surveys that they conduct (and by the way, this means, if you're making hardcore promotions, you should better pay for them). It's about posts that solely push people to buy a product or install an app, posts that reuse the exact same content from ads or posts that push people to enter sweepstakes and such with no real context. Meaning for businesses: if you want to promote something, buy ads. Since the amount of ads in the newsfeed is not likely to increase dramatically, for the user, this could play out pretty well.
