Not necessarily. It also happens to me when up- or downvoting comments. I think there are safeguards in place to prevent us from voting too rapidly. E.g. when I go through a thread and "adjust" it to my liking (up/down vote as I see fit) and then reload, then usually half of my votes didn't make it. I'm trying to get into the habit of voting immediately, but keep falling back to "buffered I/O" when I'm not paying attention...
