(The "you" I am addressing here is "me". Lest anyone take this as a veiled stab or insult.)
Something you can't do: change people's mind by Tweeting, Facebooking, commenting on blogs. At best, you can provide new information, which most will question the validity of if it doesn't fit in with their narrative construct of the universe, which will then devolve into a nit-picky dissection of what you're saying that is ill-suited to this medium. Or perhaps you provide a witticism, briefly enjoyed and then forgotten. Or - somehow - a trace of real and new insight, whose absorption is immediately inhibited by the noise of the intersocialsphere. Because real insight rarely strikes like a bolt from the blue, but sneaks up on you, grows in you over time, unless its fertilization is inhibited by a thousand conflicting thoughts.
Something you can do: take care of yourself. Escape the noise. Use this as an opportunity not to challenge other's beliefs, but examine your own, and question how you put them into practice.
Oh, and rock the hell out of the new Superchunk remaster.
