Thanks for the nice summary, Eric.
There's (at least) one category to add: people in brightly colored Hawaiian shirts, or baseball/football/hockey jerseys, with funny hats, painted hair, bald heads, kilts, clown noses, etc. These brave souls are your MCs and Game Announcers. They bring the show. Some leap, some wail, some stand on their heads -- they all wave flags, point at drive teams, and generally get everyone fired up.
Oh, and if you come to St. Louis you'll see Robot Inspectors sporting black vests over their Crew shirts -- this makes it easier for teams to find one of them in a hurry.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
