How to get to the frontpage of HN?

Hi, I read several articles on how I get to the front page of HN to present a product or whatever. It seems to be a mix of upvotes and the time it takes to get these upvotes. That's what I found out. What I didn't is which articles do really make it to the front page?! I dont seem to find any pattern after which this works.

I know I have a low karma. Is this of high importance when trying to get to the frontpage?
