Here are the most popular Marginal Revolution posts from 2010 as measured by landing pages and page views.
1. Book lists were very popular as a category. The highest ranked post in terms of page views was Tyler's Books which have influenced me the most which created a blogosphere avalanche. Links to other people's lists (of influential books) was also very popular. As was Books of the year, 2010 and peculiarly this post on The best-selling book of all time.
2. The number one linked post was What happened to M. Night Shyamalan? a one-liner and one-picturer. Also very popular in the category of "quickies" were Barbados v. Grenada, the demand for own-goals, Dead Birds, Freak-onomics, Nazi-Nudging, and Yuck_markets in Everything.
3. One Game Machine per Child on the failure of a computer voucher program to raise grades (but it did increase gaming).
7. Peter A. Diamond.
10. Why Did the Soviet Union Fall? (from 2007).
Other substantive posts with high popularity (in the top-50) were my posts Insiders, Outsiders and Unemployment and The Philosophical Cow and Tyler's posts How many children should you have?, Is there a case for a vat?, Does the Law Professor have cause to complain? and Why is Haiti so Poor?
Hope you have enjoyed this years offerings. What have I missed?
