The funny part of that whole thread was that you have to already understand how nav meshes work (at least a tiny bit, like me) in order to make the connection he wants you to make. But, if you already know a little bit about nav meshes, he could have explained what happened in a lot fewer tweets.

I don't think Twitter is the wrong format to tell this story: probably more people read it as a result, and that's to the good. But I will note that one thing about blog posts is that the format encourages editing and revision, while Twitter encourages spontaneity. In this case, the story could have benefited from a second draft for the sake of clarity.
