(regarding displaying a member's "Helpful" total)
If a member's "score" is displayed, that encourages members to find ways to manipulate the score. The Manufactured Spending crowd would be all over this, manufacturing scores in the thousands, just for the fun of it. If you think members play games to inflate post count, just watch what they do when you give them a score.
If and when a Helpful button has established a successful track record I'd be willing to run a short trial of publicly viewable score. I would not expect the trial to be a shining success, but maybe it would surprise me.
Sorry,
nsx. I misunderstood. I thought that we were considering having a "+1" or "Helpful" button on individual posts. I completely agree that there should not be totals listed by member of all his/her posts.
