I sometimes do that even for articles that aren't "Show HN". The oldest article on the newest page is currently 31 minutes, so if your submission doesn't get at least a few upvotes within 31 minutes, it will never be seen.
I've previously said that there should be some kind of algorithm for that page other than "here are the latest entries", such as "here are the randomized latest entries over the past few hours without enough upvotes to reach the front page, removing the entries that are on the front page, removing most-likely-spam entries that have at least one flag and were submitted by a new account, and (maybe) giving weight to submitters with higher account ages or karma scores."
I suppose the fairest way would be to try to equalize the number of eyeballs that have a chance to look at each submission headline on 'new'. So removing stories from 'new' once they can be seen on the front page, but also somehow adjusting for periods of low 'new' page views, and peak submission times.
I'm in similar shoes. Been working on an app for about 2 years and submitted it a couple of times after major updates in order to get feedback on the changes. After the original submission it started to just fall off the front page with out any votes or even many click throughs (according to Google Analytics). Which makes me wonder if it's impossible to resubmit something -- even if the old submission is months or years old or if it's been deleted.
Even today, in this atmosphere of upvoting Show HN posts, it fell right off the new page.
If you submitted for the purpose of feedback, I'll give you some very frank feedback. The marketing copy on the homepage is terrible. You need to speak to the potential customer in plain English. Like:
"Extract key insights from your business with an online dashboard".
The primary button that you want people to click says "warning", which tells me not to click it. There are instructions on how to click a button. The next section is why you built the business, not why I need this product.
My advice would be to read up on the basics of marketing, and then study the marketing copy on every successful SaaS business you know about.
I got 50/50 feedback on being greatest "demonstrable" and sales page comment and "what does it do?" kind of questions.
I agree the "warning" bell is stopper but again I would not have gathered interesting stats. And why does every web app have to follow each other. I like to be different and experiments new stuff. If i fail, i will make adjustments to it.
that's an interesting issue. wonder if it'd be useful (or just abused) to have a "Show HN" link-filter on top for people who are interested in those kinds of posts (which I'm hoping to Show NH something soon too, so certainly a biased opinion)
