falls habrasila. Glitch ?!

Something I do not understand at all. It was +12, then suddenly it became -1. At the same time, no one mined me, neither komenty, nor topics, nor karma. Today, put +1 on koment, power again fell to minus a little. I certainly do not care, but the sediment remained =)

upd: I’m writing to my PERSONAL blog, expressing my thoughts and arguments that everyone rushed to minus. Straight effect Habr crowd, put a minus and I will put for the company.
