Ok, been playing around with the system for a while and here are the things I learned:
1.) The system is cannot be abused too much. This is due to some limitations:
1.1) You cannot give out karma to one person continuously, ie: You like Person X's post, +1 karma. Then you don't like their post later on in the thread. You try to give them -1 Karma. You can't. You have to give/remove karma to/from other people before being able to give to person X again.
1.2) There is only a certain amount of karma you can give out, + or - in 24Hrs.
1.3) You also cannot give out more then one karma point per post. Then 1.1 comes into play etc.
2.) That they way it is designed makes you only do karma for an exceptional/really good or bad post.
3.) Be just. point 1 ensures that you cannot go overboard, but then because of point 1, why should you be unjust? You're just wasting karma.
4.)Negative karma points require a comment, to make you think a bit about why you are downvoting this person. Of course, you could put in "asdfasdf", but then you probably don't care about these points anyway.
That's it! Now give me some karma!
