As modern society spirals the drain, most products and services offered today are not fit for use by any reasonable person. So we are looking for constructive reviews of products and services here, those that are fit to be used. A post saying that yet another modern product is garbage really doesn't add any useful information since the vast majority of products and services in the modern world are worthless garbage.
We also prefer reviews of practical products and services, not products based on personal taste. So music, movies, and book reviews aren't what we are looking for.
