I recall some years ago something about how some excerpts from the memoirs of rock legend Kurt Cobain were released to the public. It then became clearly evident that stuff he expressed outside of his music, were rather lame. Coolness, it turns out, is quite ephemeral - almost illusory.
And then Twitter came along. Now it takes only a peek into someone's Twitter "timeline" to get a clearer picture of how cool -- or how lame -- they really are.
