All Roads Lead to “Philosophy”
There was an idea floating around that continuously following the first link of any Wikipedia article will eventually lead to “Philosophy.” 1 This sounded like a reasonable assertion, one that makes a certain amount of sense in retrospect: any description of something will typically use more general terms. Following that idea will eventually lead… somewhere.
I still have a lot of tweaking to do but the results so far are pretty nice.
Multiple titles can be added using a comma-separated list. JSONP requests are made to Wikipedia asynchronously, so more terms can be added while it is accumulating results.
There are some circumstances where a loop is detected up the chain. This is relatively rare. If it finds that it moves to the next link in the chain. One good example is “Telecommunication”.
