I don't bother reading comments because 99% are just "Thank you." If a prompt came up with a polite notice when they post less than the minimum number of words, Yelp gives this message: "Whoa, did you mean to post so soon? We thought your review was just getting started. Please add more details so we can post this review." Maybe add a prompt Something like: "Please give a little information why you like or dislike the item." Please explain WHY you like it? color, style, creative, texture, unique, texture, quality, words, etc.
