jack_call's Journal: The Karma System

I don't understand the karma point system. Before this I had a positive karma, I regularly metamoderate and have had my share of mod points. After this my karma is now bad.

I get a first post(on purpose, it's sleazy I know, but hey otherwise I'd have to study for my finals) and as everybody know, first posts gets heavily moderated.
I had seen the story in "the-mysterious-future" and imediately thought of a witty response, so I recited it along with some of the more tried material, insensitve clod, in soviet russia etc.
I didn't think of it as "5, Funny" but it quickly got modded up to that, of cause some people, myself included, didn't think so highly of it, and thus gave it "-1 Overrated" and "-1 Redundant". But people kept modding it up again, one guy even gave it "+1 Informative" and another "-1 Flamebait" which I just don't understand, and hope gets metamodded "Unfair"
Currently it's "50% Funny "30% Overrated 10% Redundant".
How come a post that's modded mainly positive, gives you bad karma? Is being funny really bad karma? Or is it just that funny gives alot less boost than overrated and redundant drags?

I think I get it now.

Fair enough. But I don't see how over/underrated should affect the posters karma, it's a beef between the moderators, besides as you can see from the above, it's too bland, if someone mods something overrated the next moderator isn't going to mod it underrated.
