Whoa, this is huge! I love the explanation too. The low-diameter decomposition part was very interesting. This is one of the things I love about graph theory- there are so many solved and nearly-solved problems and concepts that might be useful to each other. It's like a problem set that comes with its own toolbox to tinker with.
