Interesting... but this could become a big problem with users posting hundreds of small "haha", "I like it" stupid posts...
Maybe it could go combined with
this other post that suggests automatic rating of users by post quality. If a user is a good member (in the sense that hi's posts really contribute to the community) then we could have each of his posts count more points. Users posts with poor ratings would have fewer points for each post they make.
Does that make sense?
It does to me...
