This page needs some sort of intro/explanation about what it does.
Also some sort of explanation about how the points are decided would be nice. Some of them seem unintuitive (either in magnitude or location).
SixLinks Developers' response:
Update: Your part's been updated!
Yep, an update/minor redesign is in the works for Your Part.
As for points, the magnitudes are roughly based on the impact of the action, and meant to provide a relative gauge of an action's effectiveness. In its broadest strokes, points are there to make clear that eating less meat is much more important and impactful than changing out your light bulbs (grounded in energy use, water use, etc)
As far as location, are there particular things that people find unintuitive?
