It's already a bit flooded, but atleast not with random crap. And even if my friends would join, that doesn't mean I should follow them for no reason other than them being my friend. I guess you could make the case you can also curate your facebook feed by unfollowing a lot of friends that tend to only post shit on a constant basis. BUT fb also shows a lot of "X person commented on Y" and "X liked that" etc kind of posts that are totally useless.
