For me I know my score on HN gamifies me into wanting to spend more time on HN.
Anytime I see my score go up feel a tiny hit of pleasure and click to see why.
Looking at my comments anytime I see the score I feel proud someone liked my
comment.

While that is probably the intent I feel it's compelling me in unhealthy ways
and promotes my addiction to HN.

Mouse Capture

Mouse capture in this document means you want it so when the user clicks and drags on some element that element continues to receive events until the user releases the mouse button even if they drag outside of the element or even outside the window.

Solution:

1. On element mousedown add events to document or window for mousemove and mouseup.
