Another interesting point, jacques. Either I'm brown-nosing or you're especially insightful today :)
As I understand the algorithm, a vote on a story that has been posted for an hour and is on the way down is not the same as a vote for a story that's only five minutes old and on the way up.
As a rule I now refresh the page after voting, if the vote does not 'stick' I don't bother voting for 24 hours or so.
Since there is no clear indicator of which votes are 'real' and which ones are 'dummies' and I refuse to be treated like a six year old pressing buttons that have no effect other than 'for me' (pacifier votes ?) there may come a point where I will simply completely stop voting.
Edit: hey there downmodder, whoever you are. PG is on the record about this, I don't know where you get your information but it doesn't get much better than that.
Sometimes it takes the server a minute to catch up; have you tried refreshing after a minute or two? I've noticed this as well, but usually the vote shows up if I wait a minute and refresh.
You are assuming that your votes are actually counted, this is definitely not always the case.
I'm not seeing this. Some of what's on the site is "lazy loaded," as I recall being officially said, but to the best of my knowledge and belief a vote is a vote, and votes get counted. (There are two HN voters in my household, who visit different threads most of the time, and neither of us feel our votes aren't counted.) What would be definitive evidence of votes not being counted (as contrasted with some other possible explanations for what appears to be that condition)?
