But with a clear cut system like the one mentioned above, why shouldn't new members get to downvote as well? The system would clearly convey its intended usage, and in the process bring new members up to speed faster. If you still want to impose a restriction, it definitely shouldn't be karma based. I find it a bit counter-intuitive. [Assume maximum evil] You're going to allow someone to downvote others based on how quickly and effectively he can troll the hivemind to give him 500-1000 or heck even 5000 karma?
