Yup it's random.

Recently I posted two very similar replies. One was down voted, the other got tons of votes. My guess is the person I was disagreeing with down voted me in one, but the other one got seen and therefore voted for.

And several similar luck of the draw stories.

That’s one day too early.

Holy cow, quit whining in both threads. Luck of the draw, buddy.
