Should CJayC come up with some more rewards for having substantial karma?
Sure. The only problem is waiting for him to have the time to add them. Also, I don’t think the rewards would ever get too top heavy. Aside from individual private boards, most new features would probably have to be added to lower userlevels (should post editing and quoting ever be implemented, for example) to prevent a huge flood of people complaining that they have to wait a year to get such features. I think we will eventually see karma become more meaningful, but it’s anybody’s guess as to when.
