According to Microsoft’s new adCenter Labs Demographics Prediction tool, this blog is male-oriented with a predicted audience in the 18-24 year old range.
When we started this blog we were not targeting this demographic at all. I would predict that the majority of our audience is quite a bit older than this.

To me this is about right (at least the ordering), though I would probably swap the under 18 and 25-34 brackets (I suspect we have more graduate students in this bracket than we do high schoolers using our site).
