Facebook itself seems to be quite comfortable with the world it has created; a place where every vulnerable (and even perhaps, not so vulnerable) mind can be influenced by information regardless of factual accuracy!
I can't really tell if any particular influence floats from FB to me through my friends, most of my friends don't use FB either or their not really the type to care about things Facebook tends to influence.
If you're not one for consumerism in the first place, it's not hard to fight away advertising influence, and if you're not that active politically (although you should be!) then again, FB can't really influence you that much. You could argue that what FB doesn't show you is also a form of influence, but if you weren't on FB at all then that argument wouldn't hold.
I guess the world it's created definitely has affected me though. If it could be argued that political leaders are elected based on influence fostered on social media, I can't avoid being affected by that.
Social conversation is how you spread influence, and that's not really a bad thing in itself. What's clearly not great about Facebook however, is how you can pay for that same influence to be injected into normal social conversation.
