I love the fact that "war stories" has the highest average age (of 35).
The young guys are working on Chrome extensions, JQuery animations, HTML5 and CSS3. There are also several young users of PHP so beware :) .
This is fun to look at but I wouldn't base any conclusions on these averages. Providing histograms for each tag along with some summary statistics such as sample size, min, max, and median would give a lot more transparency into the dataset.

It's interesting as a list... and I think there's scope to do a visualization that is even more interesting (and also easier to read).
