The Vox Populi vote meter says I have cast 34 votes, but I'm being barred from further voting today because I've used all 40. Is this a 24 hours versus UTC thing or what is the reason for this behaviour?
This badge is a bit complicated because you get some votes that you can only use in a certain timeframe and only on questions. This is a feature to encourage people to vote on questions and not only on answers. If you only vote on answers for some days you at some point get a message that should discourage that behaviour a bit and that goes something like
You haven't voted on questions in a while. Questions need votes, too!
See here for more information. I am copying Monicas answer:
The daily vote limit is a little arcane. From this post on Meta.SE:
- The exact number of votes available depends on your voting behavior for the day. Concretely, there are three upper limits to respect at the same time to be able to vote.
- 40 post votes per day per user.
- 30 answer votes per day per user.
- 5 post votes after you got your first "5 votes remaining" warning of the day. If you reach 25 answer votes at time
tof the day, given
q(t)as the number of question votes cast by time
t, the total post votes limit will be no more than
30 + q(t). If you cast less than 25 answer votes, ignore this point.
So, basically, you get 10 votes specifically for questions, but you need to use them early. Once you get close to the limit of 30 unrestricted votes, you can't claim all 10 of the others any more.
No, I don't know why. I suspect it's a limitation in how voting was implemented (the 10 extra votes for questions were a later addition), rather than an intentional design decision.
This behaviour has nothing to do with the UTC time.
For badge hunters: Use all your votes on questions to get the badge. And keep an eye on Electorate:
Vote on 600 questions and 25% or more of total votes are on questions.
Voting on questions is important and these badges aim to encourage this behaviour.
I suspect that you need to vote more on questions.
See Vote Up privilege in the help center.
You get 30 votes per day to use as you please, plus 10 per day that are reserved specifically for questions. In order to meet the criteria for Vox Populi (vote 40 times in a day) you need to use all of your question-specific votes as well.
