The conversation moves too fast for the points (karma) to matter. I can't see how this would work.

Comments drop off as the conversation continues, removing any relevancy to the points. You can't "hold" highly-rated comments because they'll end up out of context.

there's also no way that I can see that this can be fixed (in its current implementation)...

if you somehow had a history of highly voted comments, you would need all the other comments to get context, but then some of those comments might be already be downvoted to hell, etc...

also, by their nature, chatroom messages are short and often only address one part of a conversation. I don't see how there will be enough time for users to provide a meaningful upvote/downvote for anything not obviously inflammatory.

This is pretty much a perfect example of an idea so bad, even its creator should have realized it and dropped it before it got anywhere near the implementation stage.

I just did it to practice my programming...

Seriously, what idea have you implemented lately?

The only possible way I can see this redeaming itself, is if the author comes out and claims that it is a joke. Meant to be a parody of other karma systems.
