I've been making a few graphs based on things I notice in the channel that I feel would be interesting to others (Or merely myself). This one is of the number of people that joined each day, based on "<X> has registered a new account. [. . .]", and the number of times people have done "~intro" to introduce them. The former is in red/blue, and the latter in green.

This one is based on the data saxjax says each night, at about 00:03, of Cemetech's stats. Stuff like the number of users, posts, words, programs, etc. Each should be pretty self-explanatory, but if you want or need any clarification on them, I'll be glad to explain better. I can say that one point of interest is in the last graph, "# of total program downloads". The large jump, and thenf all, is from some download cheating that Merth found, and we fixed.

Edit: Here's my other IRC stats topic: http://www.cemetech.net/forum/viewtopic.php?t=7996

Why is there a bump in the middle of the dl'd programs graph? It seems to me that you can't undownload a program.
