If everyone had identical criteria for voting, we would see all postings having either large positive karma, karma near zero, or large negative karma. The more alike people are in their judgements, the less information the total score provides. It is because people vary in what they find voteworthy that the whole spectrum of scores is meaningful.
As someone pointed out somewere, there is also a bandwagon effect when it comes to voting, so that posts/comments with upvotes/downvotes are more likely to continue to be upvoted/downvoted.
If many people with different criteria all like a post, chances are that the next person to read it will like it also. I don’t see a problem.
This means that a certain post which a lot of people would actually find interesting can get downvoted because of bad luck: the first voter uses non-standard criteria and his vote then influences subsequent voters.
I have often noticed the direction of karma on a post reversing after the first few votes. Sometimes I have voted on a post that I would not otherwise have done, just to oppose the trend of its karma when I thought it unmerited.
The main advantage of the present Karma system is its simplicity.
Yes! One click! A more complicated system would not be too complicated to use, but too complicated to be worth using. On Ebay, I’m happy to give feedback as positive/neutral/negative plus a few words of boilerplate, but I never use their 5-star scales for quality of packaging, promptness of delivery, etc. How do I rate a cardboard box out of 5?
In short, I think the karma system is excellent and sets a high bar for being improved on.

If you only can give 1 plus vote, 1 negative vote, or no vote at all, that seems to follow. If you rather could give, say 1-5 positive or negative Karma, we would see a greater variety of scores.
Also, note that many posts and especially comments have very few votes. This means that the votes actually cast will often not be typical of the whole population of possible voters in a system where people’s votes vary considerably. In a system where people’s votes are more alike, this obviously happens less frequently.

I agree that one shouldn’t have to rate, e.g. comments on say five different criteria. The system could be be somewhat more complex to comprehend, but you’re right that it shouldn’t be significantly more complex to use.
I think one obvious improvement is, though, to separate the posts into different categories which are to be assessed on different criteria. You could have one “objective information/literature review” section, one “opinion piece/discussion” section, one “meetup” section, and possibly a few more. In each section, you’d be rated on different criteria. That way, original pieces wouldn’t be downvoted because they’re not literature reviews, which seems to be Gunnar’s (justifiable) complaint.
This system would be superior to the present, and no more complicated. I think further improvements are also possible, but those should be separately discussed.
It is a property. It means some aggregation. But that is inevitable given a single bit.
In short, I think the karma system is excellent and sets a high bar for being improved on.
It is excellent compared to no rating or only single-direction voting. But is quite inferior to e.g. the slashdot system. Even a single-click system that provides different buttons for different types of posts would be better.
This is a feature.
