Call me an intellectual snob if you like, but I mistrust eg hotel ratings which are made by people who can’t write reasonably well.
Today’s invention is therefore to re-evaluate the ratings which people apply to products and services inversely in proportion to the calculated reading age of writers of the associated comments.
It seems that it’s not to hard these days to compute reading age, based on smallish numbers of words.
(I talked this idea over with some of the good folk at Google, but they didn’t like it).
