Is it impossible to change votes after a certain time? It should be possible to always change votes. Or, at least, this should be a site-by-site option.
If you can't change your vote, you're less likely to vote on whim. Knowing that once you've voted you can't change it means that most people will think before voting, which I think is a Good Idea.
