While you still only get to upvote once, as I understand it, that vote counts more than once based on your karma.

Regardless, while you might get high karma values based only on article submissions, that isn't going to impress anybody. When PG is looking at your HN account, he's almost certainly looking for insightful comments, vs. just a high karma score.

It's really hard to farm out quality comments to somebody else, and have it matter at the same time.

Unless there's been a recent change, each vote has the same weight unless it triggers voting ring detection.
