Does voting to "leave open" counter a "close" vote?
From what I've seen, it doesn't seem to.
How does this work?
I THINK your leave open vote will count towards removing the item from the queue, but will not undo a close vote.
I don't think skips have any effect but to let the person go on to the next question. As a mod, I skip all the time because my votes are binding. I'll cast the last or next to last close vote, but I hesitate to cast the first.
Also, close votes get stale and expire. So if you vote to close and there isn't a consensus, eventually the question gets back to 0 close votes.
