Re: I'm wondering ....
Is there a branch of mathematics which describes the hyperlink paths that are followed by someone reading mathematical articles on Wikipedia? If not, there ought to be.
Back at uni there was a game we'd play when bored after hours of 'studying' in the library. Basically, you pick a random topic on Wikipedia and see how many articles you have to go through before reaching Adolf Hitler's. The person with the least number of pages between their random topic and Hitler is the winner.
I've always been tempted to write a program that would work out the optimal paths to Hitler from any given Wikipedia article (possibly using Dijkstra's algorithm or something similar).
