Tip of the Day

If you really hate something and write a negative review, do not use good grammar. Research has found that negative hotel reviews with good spelling and grammar actually increase demand for the place. We don't know if this applied to all products, but it seems to. The key seems to be that 

reviews that rate products negatively can be associated with increased product sales when the review text is informative and detailed

which seems to confirm the old dictum that any publicity is good publicity. When people know more, they feel more comfortable buying, even if the knowledge is negative. I would guess that the negativity of the review serves as a signal of honesty, you know that the detailed information is not coming from a shill so you are more likely to trust it.
