Hacker News Reader

From what I can understand, looking at one site that uses the button[0], it just displays current votes and links you to the submission. It doesn't do any voting from the site like a reddit button would do.

My answer to GP looks silly now. I see what he meant. The submission title should change to vote-counter button to avoid the confusion.

I also don't understand how it works. If you could up-vote just by following a link, you could easily gain a system. For example, you could submit a story that automatically up-votes itself when visited by logged-in user, without any button press (CSRF). I believe Facebook like button (and other similar gadgets) are iframes from Facebook. So Facebook controls how the button looks like and it is not possible to submit 'Like' requests from a third party domain.

EDIT: This is a submission from a while ago that does, in fact, upvote itself.

They use the search API. https://github.com/igrigorik/hackernews-button/blob/master/h...
