Rands explains the intellectual and creative home of a nerd:
My Cave is my intellectual home. My kitchen is where I eat, my bed is where I sleep, and my Cave is where I think. Everyone has some sort of Cave; just follow them around their house. It might be a garage full of tools or a kitchen full of cookware, but there is a Cave stashed somewhere in the house.
It’s an ominous name: Cave. It alludes to a dark, damp place where you are likely to be eaten by a grue. The irony is that the purpose of a Cave is not to insulate, its purpose is to germinate.
Only a true nerd could get every last detail so right.
