TBH I think the network effect that helped Facebook boom is now working in reverse: FB full of crap -> people post less updates from their personal lives -> there's less to read for their friends -> people visit less/update their feed less.

So even if what you want is possible, it'll probably be quite barren in there.

Yeah, it might very well be that they flood the timeline with crap to hide how little actual content there is left by now.

Still, this might or might not be the case. It would be really interesting to see some kind of study that would analyse how much non-commercial content is still posted on Facebook - but I guess Facebook would fight tooth and nail against anyone actually attempting that.

+1, I have been looking for this as well. I'm keeping FB because I'm member of a few groups that really post interesting content. However my feed is flooded with random crap that FB hopes I might like better.
