Yes, great comment. I knew it would be good as soon as I say that it was rated +2.
Seriously, though, showing votes for only your own posts would probably be a large improvement. Why are votes even visible? Make it so we still can have a comment rating threshold, but can't see karma otherwise.
The anti-kibitzer will do that, though it also hides poster names (which I felt was preventing me from getting to know anyone). It's accessible from your account settings.
(Edited for politer tone)
I'd like to see, beside the cumulative karma as it is now, also its analytic. Does my 0 points somewhere means no upvotes and no downvotes or +7 and -7, for example?
A timeline graph would also be appreciated.
