The rewards of owning a high-karma account are limited. You don't get to upvote a frontpage item more than once (or do you? not at 780). Your comments may receive an occasional fanboy upvote, but that only creates more karma and doesn't shift the visibility of your message by a large amount.

So in conclusion, I don't think HN accounts will be traded much. Perhaps more if the frequency of "free invites to our beta service for HNers with 1000+ karma"-promotions increases.

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.
