I suspect these social networks don't really care, but I block any and every "public" facebook page that gets shared in my feed. Of course, you still see "what was your first car? from 93.7 THE OCTOPUS Des Moines, or whatever page you haven't yet blocked, but at least it gets rid of the worst, most-often shared offenders like the ones you cite. I'm assuming Twitter doesn't let you do that, though. I wish Facebook would give you an option "never ever ever show me anything from a public page". I will never care that a friend shared or posted on a public page. I will only ever care about their own content, and the groups I choose to be a member of.

(Incidentally, this is more broadly my problem with the default-public nature of Twitter).

I just wonder at what phase of growth-and-bust the networks will start to care a bit more about serving the demands of their eyeballs.
