When I talk about Meta here, I mean any meta but this one.
I understand the Idea behind “Your vote is now locked in unless this answer is edited”. However, I don't think this reason applies to meta sites and have some reasons why I think votes on meta sites shouldn't get locked:
Opinions change:
I thought a feature-request was just stupid and I downvoted it. Later on, after reading the answers, I saw the ideas behind it (which weren't included in the question), and wanted to upvote it - but I couldn't. Of course, the question was written badly, but ...
Votes on meta work in a different way,
as they indicate (dis)agreement instead of usefulness. So in my example, the question wasn't really useful as-is, but I did agree, after hearing the ideas behind it.
You don't get reputation on Meta,
so there is no reason to tactically downvote1.
So,
What would you say of disabling the lock-vote feature on meta sites?
And no,
There is no problem with users who go bumping posts by up- and downvoting all the time (as suggested in the comments) since votes don't bump - thanks Hugo and cpast.
Some very clear examples of when you want this
Moderator pro tempore elections - what if a nominated user does something stupid and you want to remove your upvote? Nope, too late.
Feature-requests can get more useful after a new feature implemented (e.g. when there's a request for changing the footer that you downvoted, and then the team changes the footer in such a way that you want to upvote it instead)
1: as Shog9♦ points out, there still is a reason to tactically downvote: when you've answered a question yourself as well, then downvote the other answers to get your answer shown higher. I don't think this is a real problem with this feature-request, but a problem we have now too and will probably always have.
status-completed
