A person is not a face.

Dating sites of all shades "sell" us a person at various levels of depth and according to our interests.

Our interests can be deep, or can be shallow.

Tinder is "selling" shallow+fun (Appearances, nearness, sexual adventure).

Shallow + fun sells. Look at a magazine.

Eigenfaces takes the idea a step forward. Automate shallow+fun+selection.

Remember the vaporized alcohol craze ?
