The thought of just an add-point selection is entertaining. It seems no hating can come of this. Instead of quoting a person and replying to a post with only a comment like "good point", one could simply click the add-point button. Perhaps some of the more helpful posts, which have been thumbed-up a specified number of times, could stand out against the rest. A thumbs-up icon seems appropriate for this, or, to make it cute, the points could even be considered "wags" using an icon resembling a tail. This seems very appropriate, if just, for the arts sections... but then it seems there must be a scaled system, like 1-5 stars (or paw-prints). It doesn't seem fair to judge art on a "love-it or hate-it" scale. I have often wished there was a star-rating system for the arts.
However, this all seems like so much work involved for what might end up tacky, like a wannabe YouTube-ish feature. Do we need to search posts based on rating? Is the number of replies to a topic not enough to rate its popularity? Is there reason for ranking users based on "likes" enough to warrant such an undertaking? Is it not already obvious who contributes most, speaks (writes) intelligently, or who to ask questions or report problems to?
I understand seniority and number of posts do not necessarily stand for intelligence-factor or level of contribution, but is it really necessary to introduce an open rating system to an already content community. "If it's not broke, don't fix it," might apply here.
I have thought about the user's join-date and think it would be helpful to display this with their display information next to posts.
Blah, I've lost my train of thought. Anyhow, as neat as this would be, it might just be unnecessary.
