I've been giving the following post list to friends, to get them into LW:

1) The Twelve Virtues

2) Cognitive Biases Potentially Affecting Judgements of Global Risk

3) The Simple Truth

4) The Useful Idea of Truth

5) What do we mean by rationality?

6) What is evidence?

7) Rationality: Appreciating Cognitive Algorithms

8) Skill: The Map is Not the Territory

9) Firewalling the Optimal from the Rational

10) The Lens that Sees its Flaws

11) The Martial Art of Rationality

12) No One Can Exempt You From Rationality's Laws

I'll occasionally adapt it, e.g. Swapping the first two posts around, for someone who has an academic background and will be more interested in an academic paper to start with.

Anyone looking for my current, extended version, can find it here.
