Looking at the [uptick in visitors](http://johnaugust.com/2012/2011-by-the-numbers) for 2011, I speculated that it might be because of Twitter.
I had Ryan pull some numbers, and my new theory is much simpler: more posts means more visitors. The number of visitors was down slightly for 2010 because there were fewer posts.
