OK, OK, I know I'm a day late. But aren't I always?
In honor of the eighth year anniversary, I'd like to offer this graphical history of user sign ups. In the past dmsilev posted several graphs like this, but he has been pursuing other interests for a while, so I thought I'd better step up.
Explanation and larger image when we get back together on the other side.
To see the promised larger image click on the image in the intro.
Time is on the horizontal axis, intervals of one year are marked.
Rate of sign up, number of users per day, is on the left hand vertical axis.
Total number of users signed up is shown on the right hand vertical axis.
The gray curve shows number of users signed up since the scoop version started in late 2003. Purple crosses are included every 10,000 uids (a table with this data is shown below).
The red curve shows the rate of sign ups over time. There is a "background" rate of 50-100 per day, with many little spikes into the 100-200 per day, and several major event related spikes. These events correspond to moving to scoop (2003), the presidential election day of 2004, the Yearlykos conferences in 2006 and 2007, and (thank you Sarah!) the Republican convention of 2008. The largest bump in signups in 2005 came about a week after Hurricane Katrina, 9/5/2009.
The green curve shows the rate of sign ups by new users with a name consisting of some letters followed by some numbers, followed by some more letters. I've indicated these as "abc123def" type names. It is apparent that the very recent increase in the rate of sign ups for these names is far above normal. It very likely this reflects a scripted attack to generate a large number of daily kos "users". I don't think this will be much of problem to ct et al.
A table of date of sign up vs uid at intervals of 10,000 follows.
