Link Exchange

• Bryan Caplan on libertarians quoting Trotsky. No, this is not fake.
• Athletes, performance, signalling and "excessive celebration," from Robin Hanson.
• In the next week, we celebrate twenty years since Die Berliner Mauerfall. Links, all good, from Cato@Liberty. I particularly like the one about "paradise imposed at gunpoint."
• Interesting map of the Biblical flood that shows a lot about faith and science in the seventeenth century.
• Exploring the pros and pitfalls of Wikipedia. I think the demographic data is particularly illuminating.
