I'm thinking of a system where you'd have classify the post you were reacting as "on-topic" - electronics, or "science", "culture", "politics", "recycled propganda" or "personal abuse/flattery" and rate it on a five point scale, from useful (+2) down through helpful (+1) through neutral (0") to unhelpful (-1) to misleading (-2).
