The treasure deep inside us
I'm more than a little late, I know, but this essay on Joan of Arc is easily the best thing I've read that was written in response (in some sense, at least) to the shooting in Tucson (although if you want something more direct...).
I am unabashedly a cat person (not that I mind dogs or dog people, that would be stupid), so I definitely wish that this, as excellent as it is, had a more general form.
I think I probably blogged it when someone posted a Justin Bieber song slowed down 800% or whatever it was, but clearly that had nothing on the same trick done to the Jurassic Park theme.
