I think if it's interesting, it will get to the front page. Submitting to HN is not really a contest, just share with us what you think would interests us.

Of course, there's some basics to make it more attractive, like a good formatting if you're adding a comment to your submission or maybe start a discussion related to your link (if there's one).

You should always try to make it more easier and enjoyable to read. Hope this helped.
