Is asking your friends to vote your HN postings to the front page ok?
mcantor: I'm surprised that there are no voting systems which simply detect cliques, and make your votes weaker when you're voting for someone in your clique.That is, the more you vote for someone's submissions, the less "power" your votes have when voting on them.  As long as you balanced it correctly, you would maintain the theme of compelling submissions hitting the front page while removing clique-based vote problems.If someone is so awesome that everyone upvotes every single submission they have, and are thus part of their "clique," it still wouldn't be a problem, because there would be enough people upvoting their submissions to counteract the juice being removed from their individual votes.
