I was just playing around with BigQuery for the first time, and I decided to plot the number of unique commenters per day. It seems to have a significant dip in 2014. Does anyone remember what happened that may have caused it? I have been around since well before then but I can't remember anything that may have caused it.
Here is a link to the data: https://docs.google.com/spreadsheets/d/15dG-YDAgHaF_Da0dADYJGz_vWUEw49dbDFQhCvPvRVI/edit?usp=sharing
