Hope your product is in line with the HN's audience - but having said that, many HN users (I believe) are interested in startups in general, so I find it interesting to see what areas people are trying to innovate. I posted a link to my project (http://www.sideprojectors.com http://www.sideprojectors.com) and received a few hundred signups. I found them more than sufficient to do my beta testing. It's not really the initial post that matters, but what you do with them after your launch. Even if you get say, 100 users, they are GOOD 100 users! (better than zero!) and if you believe in your product and continue to iterate + get feedback from them, I'm sure you can take your product quite far. Of course, you'll need to do many other things.
