I almost always repost 1-2 times when I have something "big", unless the 1st post hits the home page of course. Most of the times I try a slightly different angle, maybe a variation in the title. It definitely works, in the sense that sometimes you're just unlucky and maybe your post is hidden by big-Co news. I definitely recommend to not exaggerate though, if a post doesn't work, it simply doesn't. Also, I don't think it's about the algorithm, but I generally see some sort of correlation between me commenting around and my posts getting higher results. It might be that people look at my profile and/or I'm more "in the HN lingo" and thus my posts resonate more. So my recommendation is to participate in the community, not just post + repost blindly.
