Can the websites you visit predict your political leanings? That's the claim of Engage, a digital agency that says its algorithms have mapped the politics of the social web.

Users of services on the left of this chart are more likely to vote for Obama, while users on the right are more likely to be Romney supporters. Services higher on the chart have more politically engaged voters, while those on the bottom have more politically disengaged users.

Engage got the results by monitoring thousands of Facebook users and their "likes" using a program it calls "Trendsetter," which it claims tied together "polling, social influence data, and consumer preferences" to deliver the above results.

While the results are interesting, the methodology certainly raises questions.

First, were enough users of each platform involved in the study to deliver strong results? (Reddit, for example, is shown to be politically inactive, but there's a very active political community on the site. The same is true of Tumblr.)

Second, do traditional polling factors such as age and income level predict what digital services a person might use, making them a better predictor of political persuasion? (A younger person may be more likely to use Spotify , and to vote for Obama, making these results spurious.)
