I am interested in knowing how many users on Programming Puzzles and Code Golf change their default sorting preferences for answers. More specifically, I want to know what those sorting preferences are and what percentage of users use each type.
I first thought the information might be stored in a cookie. I changed my sorting preferences, cleared my cookies, and loaded a different question (to avoid being fed a cached page). My sorting preference was saved.
I checked Data.StackExchange but didn't see anything that looked remotely like sorting preferences.
Where is this data, and can I access it?
