The idea of letting people vote "helpful" or "unhelpful" on reviews may have been a good one, but it doesn't seem to function the way it was intended. If people like you or agree with your review, they may choose a "helpful" vote. On the other had, if people dislike you or disagree with your review, they may choose "unhelpful." In practice, whether a review has been voted helpful or not seems to have little to do with the quality of the review. I propose that TA do away with the "helpful/unhelpful" votes, as they seem to do more harm than good. Discussion, anyone?
I did a search on this forum for this topic, and was surprised to come up empty handed, as I thought this was something that had been discussed.
