Mint, as the name so cryptically implies, is designed to give you a “fresh look at your site”. A slice in time, if you will. Where has my traffic from the last 48 hours come from? What days of the week does activity on my site peak? What terms have people possibly been searching for that could lead them to my embarrassment-of-a-website?
Mint grew out of a desire to maintain a rolling window, or dashboard, of activity with which one could easily analyze what’s going on in the here and in the now. Not so much in the two years ago. It is this philosophy which allows Mint to maintain such a small database (generally around 20 megs, but fully customizable) and yet provide such great functionality.
