Facebook has its uses (acquaintance address book, private message with people you know or knew, local groups) but don't try to make sense of the feed because it's hopeless, no matter how many tweaks they do to their algorithm it can never be more than an amalgamation of the lowest common denominator, IMO. Though I guess YMMV if you have extremely interesting acquaintances, but I'd be surprised.
I imagine even if you have extremely interesting acquaintances with interesting things to say, they are more than likely saying those things places other than Facebook.
Heh, I still remember how much I disliked the Feed when they introduced it. In retrospect, of course, I was wrong: no matter how much I thought it was a disaster, it was a huge reason for Facebook's rapid growth.
It'd be a bit amusing if what has been the reason for their growth eventually ends up being the reason for their decline.
