The original link works (for me), it just directs me through a captcha first. That's not a broken link by the usual meaning of the phrase, it doesn't mean people weren't reading the post...
The former. I for one happily upvote a submission before reading it, to keep it on the front page which is so fragilely ephemeral for new submissions, so I can read the article and then come back to (hopefully) some good comments from others in the thread.
