Yeah, I know the "rules". Point is, everything at big think is a video.

Funny how I had 21 karma points before I posted that comment, which got 4 down votes and another comment got 3 upvotes, but now I have 15 karma points.

How does 21 - 4 + 3 = 15?

1) I've never heard of BigThink.com before.

2) I very often open many links without thinking about which domain it's on.

3) A post's karma will never show below -4, even though the real karma could be way lower.

Months ago -8 was the limit. Really, what's the point in limiting the display to -4 if it's really minus n? Why not just show minus n?

A score of -4 is actually -5 karma points (since everything starts at 1 point).

Here's a tip though - you can't cash it in for prizes, don't worry about it.

And 1 point is actually zero. Now I'm down to 4, so 15 minus "5" plus 2 = 4 in hackernews math?

For the record, I don't care about karma points, I care about whether or not the system works correctly.

Have at it
