Turns out we have it at home already! I’m making mix tapes (aka stacks of books) for my partner from my back catalogue and he’s making mix tapes for me. I sometimes start salivating when I walk in the door and look at the stack of books on my table. Although it’s often weeks before I get any reading time.

In economics, the bottom of the pyramid is the largest, but poorest socio-economic group. In global terms, this is the four billion people who live on less than $2 per day, typically in developing countries. The phrase “bottom of the pyramid” is used in particular by people developing new models of doing business that deliberately target that demographic, often using new technology. This field is also often referred to as the “Base of the Pyramid” or just the “BoP”.
