Please remember that we're supposed to be able to submit links, not just original essays. Anyone downvoting on that basis (rather than dislike of the link itself) is making an error about Less Wrong posting policies. A link like this wouldn't be promoted to the front page but it's okay to vote up if you like the content.
Why cant linked articles be promoted? Do they have to be original content written specifically for LessWrong? Can they be cross posted elsewhere?
I'd be really interested to hear what the Less Wrong community thinks of this. Don't spoil it by reading the comments first.
