I actually tend to find those pretty demotivating/bad-behavior-inducing as well. Reputation in the actual sense is one thing (getting a reputation for being a good contributor), but I really dislike karma/points-style "scorekeeping" and up/downvotes. Fortunately on HN nobody takes it seriously, or it could be a problem.
Wikipedia does have miscellaneous scores and badges, of which I find the badges awarded by community members as recognition of a contribution most useful: https://en.wikipedia.org/wiki/Wikipedia%3ABarnstars
There's also just raw counts of contributions, which everyone takes with a large grain of salt:
You can also click "thank" next to specific edits, which just sends the person a notice that someone appreciated their edit. That I think is useful, but I'm not sure how useful it would really be to keep a score of "number of thanks" or whatever. The point is just to say "hey someone noticed you did a good job here and appreciates it" to give some encouragement, not to keep score of who got thanked more.
And finally many people just collect vanity "hey look at what I've done!" lists, which can be a nice way of reflecting on your contributions and feeling good about them. Many people's User Pages are like that, or you could do it externally like e.g. http://www.gwern.net/Wikipedia%20resume
