Any way for at least the mods to see who -1'd stuff? Or at least the admins?
So are we really going to start having karma/respect police now? 
Letting mods/admins see it (I'm sure admins can anyway =.=) would reintroduce people being unwilling to -1 a post. If people knew that I could see if they -1'd me, I think they would think twice about doing so, and hence create an unfair buffer between mod/admin posts and normal members.
Well I don't think it's going to be something we're going to be particularly strict on. Myself and I assume most of the other mods generally don't bother acting in grey areas due to the difficulty in making a correct decision, or just laziness (i.e. me). But if there's blatant abuse of the system as has happened to pi, then that's when we could step in I guess. There's nothing wrong with giving a -1 if you actually believe the post actually deserves it. Once again, if it's a grey area then it's unlikely it'll be challenged. But I don't think the border between helpful and unhelpful is that grey at all. Most posts that have been downvoted so far have understandably been downvoted and that's why I haven't cared. But if there's blatant abuse, someone needs to know about it. I just feel that people are downvoting on the basis of who the poster is right now rather than on the merit of the post itself. There's definitely several members being targeted at the moment. Perhaps just let us see who's been doing the voting in something a little more out of the way (profiles, admin tabs etc) so that we're not constantly aware, but can check when need be.
But overall, I'm still questioning the usefulness of this system. People seem to have a far higher inclination to neg than to vote up a post. I've noticed many posts breaking the -5 mark whereas the +3 mark is rarely ever broken - even for very helpful posts. As with life I guess, people are far more inclined to give criticism than praise, especially anonymously, and this is essentially the reverse of the karma system where the majority was praise. I feel this is just going to make things really negative around here. I can foresee this turning into a massive bitchfest-downvote-retaliation party some time in the future, where people are just going to downvote each other for the hell of it because they suspect the other person's been doing the same. For this system to work, it really depends on more people voting because I think it's quite evident even without knowing who's been voting that the numbers are currently being dictated by just a select few really. If more people voted, these grudges wouldn't really matter too much because the effect of their vote becomes negligible. But really, I think the system needs to change somewhat because this isn't working too well and won't even if the mods can see who's been voting. We can't exactly force people to vote either, whereas an incentive to vote doesn't work all too well either. So yeh, I'm not exactly sure what there is to do to fix it...
