I think that the issues people have been having with karma spontaneously dropping should be fixed at this point. There's been an overhaul of most of the moderation/meta-moderation/karmic system. We'll see how it works. I also artificially bumped the karma of those I thought may have been affected, to make sure more people could start discussions.

In the meantime, you have this discussion to enjoy. To start you off:

stuff sucks! discuss.
