If people agree with this, what are some strategies for countering the trend? People could put more effort into down-voting unconstructive comments. Maybe up-voting should also be unavailable until a karma threshold is met. Maybe up-votes could be made precious by limiting the number per day. Maybe there could be honeypot content that's bad on purpose, or determined to be bad after the fact, and everyone who up-votes it gets their voting privileges revoked. The nuclear option might be to hide scores even from ourselves.
