Anyway, analogies are imperfect, please look in the direction where I am gesturing, not at my exact words.
The point here (and of the entire conversation) is that you shouldn't judge a medium by its worst imaginable actors as long as you're given the right tools that allow you to use that medium undisturbed, effectively putting them into a different silo. Today twitter allows a very crude, imperfect approximation of this by following people that post decent content and setting the homepage to "latest posts" instead of "top tweets". Ideally we'd have better tools than that.
