Let me update my pop tracker with a 1 year image instead of 6 months, will update this post when that's done. Here is a link to the tracker otherwise:

Out current growth rate is higher than last year's winter (this time we have Ninja streaming instead of just a Kotaku article about the server). Pop did plateau over the summer, but it always does.
Overnight dips are now higher than 1 year ago's peaks - and we have about 2x as many players on at peak instead of 3x at peak a year ago. This means we have more players from all timezones, too.
Overall things are going great. I keep telling nas we might hit 2k by the end of the year.. we'll see. If that happens, we'll have exploded to 5x the peak since last year...
