Generally, I look the number of page views per day or week and which post people are reading the most. Occasionally, I look at the traffic sources for my blog to see how people are getting to Beer on my shirt...
Usually, it is pretty straight forward - Facebook, Twitter, Elephant on Fire, Beer and Whiskey Brothers, etc.
Today, someone got to Beer on my shirt from the Montel Williams wikipedia page. This is my new definition of reassurance.
(how does this happen?)
