What can it teach you? Me - never try and say anything insightful, that's boring.
lowest lows - responding to anything antagonistic, talking about "things I like" which I haven't really grown to like that much, half of my opinions are half-formed mounds of half-bullshit, Animal Collective talk, Post Rock talk, too many "LOL"s, too self-indulgent, too self-aware
Highest Highs - swearing, enthusiasm (if this was a venndiagram this would cross over heavily with AC talk), general greatness which weirdly doesn't transmit over the internet.
DiSers who I know, analyse yourselves for my amusement.
