(this is not shameless self promotion)
I've done up some graphs to show how the Stack Apps sites are all ranking against eachother. You can check them out here.
The face of the matter is that Pro Webmasters is one of the oldest sites and we've really levelled out in our volume of questions over the past two weeks.
So this is a bit of a gee-up to encourage others to really try and get the site moving again. I want to see a huge upward swing in the question volume over the next week!
Update: I aplogise, I think I just got a bit freaked out when I first saw the status. I think I overreacted, and after reading through everyone's responses below you've all raised very good points. Thanks everyone.
