In addition to removing the slider, it also could help to find a way to quickly sum up the benefits of the site using a very short sentence instead of a paragraph.
Truly and honestly, if you don't have a product that is perfect for the HN crowd as a niche, it's still important to get on the front page if you can take feedback well. It's the best you'll ever get, it actually may make or break your business. If you don't get it here, get it elsewhere and fast.
I myself always visit the sites but I cannot remember I have been using one for longer than a day.
My 1st two start-ups made the front-page.
My current and I think best yet hasn't had the same good fortune.
good luck to you!
Our web app turns a crowd & their devices into a huge stereo system; all devices play same audio in sync.
We think it's cool, but maybe people don't see it being useful? We use it at home to fill our house with audio.
btw: You summed it up pretty nice in your blog post!
