To me it still feels like the polite thing to do to follow back if somebody follows me - it is like answering "hello" if somebody says "hello" to you. No, what you're doing is more like inviting someone to your house for dinner because they said "hello" to you. At any rate, I've found my life to be drastically simpler than many reports of social-media use, and I attribute it largely to the fact that I only follow/friend/whatever people I know and like.
