We can change our vote in other websites, but we can't do it in codeforces. So Why? There can't be bad thing by changing our votes.

 
 
 
 
  • Vote: I like it
  • +68
  • Vote: I do not like it

It forces you to think twice before voting.

    Typical counterexample: initially you want to upvote someone. Then it is revealed that this someone was actually lying about something, now you want to downvote. It's important to think twice but you're not expected to have perfect knowledge.

    I think most CF users don't think even once before voting.

Yeah. You should know what you want to do clearly before you vote.

@people_above, so editing comments is allowed but changing your vote is not? :D

A reason is likely that it isn't trivial to implement. But yeah, we do need this feature.

    Changing a upvote to downvote means adding -2 to the overall votes and vice versa for the second case. How is it difficult to implement.

      Contribution is more complicated than just upvotes minus downvotes.

        May be, but contribution is surely a trivial thing. What do you think Contribution master

    you can see history of a comment

    so upvote / downvote must too (0110101)

Also about votes: am I right that I can't easily determine if I've already voted for a post, but can for a comment?

If it's true, why so inconsistent? It shouldn't be difficult to implement.
