I had the same thought as yan: simply find the opposing side of whatever your belief/comfort. However, I guess you really want things that are dissimilar rather than opposite. That's tough, but I see what you mean. For example, I recently learned a great deal about economics, which can be fascinating to understand, and how it's connected to governance/politics. Yet few politicians truly know economics, as even President Obama admitted to knowing little about (but learning) in an interview. I guess for an algorithm my approach would be to start amassing pages on different topics like Google, then look for commonalities for alternative subject matter. It would still be tough to make certain connections, though, like the example of economics and politics (during times of non-crisis).
