Not really related to the content of the article, but my pointer wandered over some dot on the page. Suddenly it started animating, with the caption "DON'T MOVE." So I didn't. Then it changed to a checkmark, with the caption "SENT." What the hell did I just do?
You sent an HTTP POST to http://dcurt.is/stealing-your-address-book/add_kudos. This results in incrementing the "# KUDOS" number under the dot. He seems to have built his own "like this" button, essentially, with a like counter.
