Every post is a repost of a repost.

Would you not agree that this is true most of the time anymore with most sites? (aside from news sites)
Most of it is unoriginal, rehashed material with some of it having a slightly different spin. I'm sure my post has been posted dozens of times over, some agreeing with it, others disagreeing with it. Hell, there might be someone that posted this with an entirely different opinion! People like normalcy and fear change, and I don't think it'll change anytime soon.
