One thousand posts
I just realized with this post, I will have 1000 posts. Here is the histogram distribution of the text file size in kB for a random sample of 150 posts:

Counting 5 characters per word, the average of 4.4 kB is equivalent to about 900 words per post. That means I've written nearly one million words (given the margin of error for a sample size of 150 is about 1/√N ~ 10%). This is on the order of about 10 doctoral theses in physics.
Here's a list of my most popular (by pageview) posts:
More like stock-flow inconsistent Mar 3, 2016Â
This analysis is so bad Jun 19, 2015Â
The irony of Paul Romer's mathiness May 16, 2015Â
Mark Thoma, information equilibrium is the model you're looking for Apr 7, 2015Â
Keen, chaos, and equilibrium Oct 5, 2016
As several of these irritated their subjects, I think this list is better described as the top five most infamous posts. Only the one directed at Thoma could be considered positive. Apparently criticism works best.
