I got a 1 cent vote ( http://www.steemdollar.com/dollar_per_vote.php?name=ottodv ) by investing half a Bitcoin. Although strangely I don't see my vote increase the balance every time (I guess the formula is more complex).

It is kind of nice to have your vote be worth something. Nothing like a whale maybe, but my little vote can at least help get the ball rolling a little bit more now than before.
