Like millions of other website owners, we use Google Analytics on this website.
Google Analytics is a piece of software that grabs data about my visitors (you). It's something like an advanced server log.
The tracking information allows me to better understand the kind of people who come to my site and what content they're reading. This allows us to make better decisions about design and writing. Occasionally, we will compile aggregate statistics about the number of visitors this site receives and browsers being used. No personally identifying data is included in this type of reporting. All of our activity falls within the bounds of the Google Analytics Terms of Service.
