Yea, I do that a lot. But I also suspect that sometimes I though I hit the upvote button, but HN registered it as a downvote anyways. Both of the buttons combined are smaller than the tip of my finger, and they both disappear as soon as one is tapped :(

The text for an upvote is “unvote” and for downvotes is “undown”. So if you check that you’ll see which you did.

Oh, awesome, I didn't realize that!
