I don't even look at my news feed anymore, nothing but spam. It tends to show me links to things rather than the user generated content that I want to see. I think the same happens in reverse, I rarely post because my posts are making it to my friends news feeds.
I configured facebook to add notifications for a handful of friends and family members that I want to see posts from.
Once or twice a week I skim the facebook notifications page, ignore anything that says "shared", open the few "updates" and then I'm out of there.
I think the social network is dead, and there seems to be nothing else out there to take its place. And even if there was, everyone over 20 is only on facebook.
