in reply to Challenging votes
I see a whole lot of problems with this idea, fueds starting (fine! so and so wants to vote me down, I will vote them down), feelings hurt(some newer monk having a saint they respect "constructively critique" code they sweated over for 4 days). Perhaps rather than doing a challenge, why not have a comment as part of voting? Perhaps when you click a ++ or -- there was a second page after you clicked on vote for reasons- have a few drop downs for ++ ie.
And we could have the -- comments
And perhaps at the bottom we could have a simple text area for comments that do not fit there.
Perhaps there would be some way to keep a ANONOMOUS record of these comments. When a person looked at their nodes, there would be a little table that said x++ votes cited..., y-- votes gave this reason etc. Perhaps anonymous "reasons" could help some people without them having a fear of retribution. I think this will not alleviate all of the problems that there is with anonymous voting, it may help.
