How clearly this product explains itself, as a weighted total of the seven answers below. Not a review: Jev reads the landing page, it does not use the product.
The shape of this score
One axis per question, each from 0 to 100. Further from the centre is better on every axis, so a large even shape is a product that explains itself well on all seven counts, and a spike is one that does a single thing clearly and the rest poorly.
The buzzword question is drawn inverted, so a long spoke there means concrete detail rather than hype.
