The things I and my friends occasionally post on Facebook are buried by all the newsy stuff and likes. Stuff that surfaces is just superficial (selfies, landscapes, food).
I think this is only partly due to FB's timeline ranking. Posts there potentially go to everyone you've ever met, so you're not likely to show yourself as vulnerable/too weird. Maintaining groups for close friends and family feels weird too and like a lot of work.
I guess it's back to email.
