You shouldn't be able to like your own post

Nobody cares about the voting of posts anyways, so it's a moot point.

 

You can do only once per post, no big harm can be done; be your guest. Just ignore the number. It's a relict from times where unneeded down voting could be compensated. Just ignore.

Did you up-voted yourself

 

The real problem is that once you've up-voted a post, unless you remember which thread it was in, there's no way to undo it. We need a way to be able to see all posts on which a user has up-voted.

 

I up voted you post because I thought it was correct.

Now i've up voted MY post because I think i'm right !

 

Well that's because they make the mistake of taking things on the internet personally.

 

It's good to have high esteem for one's own opinion.

 

I down voted your post because I think you are wrong.
Alas I have to keep the running total in ram. It is terribly mentally taxing.

 

Yeah, it is odd, but just subtract by 1 for every post you read. It'll even out.

 

Thank goodness you're here to point out all of the fallacies of the site!
Few, if any, should care about the voting.
