Kevin Schroeder has a quick post to his blog talking about the integration of job queuing he's done with his WordPress blog to build a list of popular posts for his sidebar.

One of the things I liked on my old blog was the ability to have a Popular Posts section that was based off of Google Analytics. [...] So I had missed that, but it was not overly important so I left it. But yesterday was a day where I needed something that was both engaging and brainless to do. So I decided to implement my Job Queue API code for WordPress so that I could write a WordPress widget that would put the popular posts in the sidebar.

He's created a plugin to handle most of the heavy lifting for you.
