The IRC stats page features daily statistics from the IRC chat, generated by Anthony. Everything from top nicks to most used words can be found here. The people who are in the Top 20 can look at your own personal stats.
The IRC Stats first started the day after the IRC was available. It had a bunch of stuff like the top nicks,the relationships between them and much more. In November 2012 the stats stopped for a little while. They came back in January 2013 for [I FORGOT I WILL ADD LATER O3O]. A few days after the stats got a new design and new stats.
