In my upcoming CHI paper, “Presenting Diverse Political Opinions: How and How Much,” we used Amazon’s Mechanical Turk (AMT) to recruit subjects and to administer the study. I’ll talk a bit more about the research questions and results in a future post, but I’ve had enough questions about using Mechanical Turk that I think a [...]

In the visualization in this post, the edges between blogs (the nodes, colorized as liberal, independent, and conservative) are weighted as the [...]
The first of my social software for wellness applications is available on Facebook (info page).
Three Good Things supports a positive psychology exercise in which participants record three good things, and why these things happened. When completed daily – even on the bad days – over time, participants report increased happiness and decreased symptoms of [...]
Last week I presented our first Sidelines paper (with Daniel Zhou and Paul Resnick) at ICWSM in San Jose. Slides (hosted on slideshare) are embedded below, or you can watch a video of most of the talk on VideoLectures.
Opinion and topic diversity in the output sets can provide individual and societal benefits. If news aggregators [...]

These visualizations are based on graphs of when one blog [...]
I was pretty excited by the work that Andy Baio and Joshua Schachter did to identify and show the political leanings in the link behavior of blogs that are monitored by Memeorandum. They used singular value decomposition [1] on an adjacency matrix between sources and items based on link data from 360 snapshots of Memeorandum’s [...]
Tagged BALANCE, blogs, linking, news, opinion, politics, researchWorking with Paul Resnick and Xiaodan Zhou, I’ve started a project to build political news aggregators that better reflect diversity and represent their users, even when there is an unknown political bias in the inputs. We’ll have more on this to say later, but for now we’re making available a Google gadget based on a [...]

In addition to presenting a short paper on the use of a wiki to enhance organizational memory and sharing in a Boeing workgroup, I participated on the WikiFest panel organized by Stewart Mader.
Since then, a couple [...]
