Had a look at the first four pages of launchly.com. I wasn't near enough tempted to look at any of the sites. I'm sure that the visitors to that site are very different to those who regularly visit HN. For me (and that's only a single data point) HN provides value that matters to me. Launchly, on the other hand, doesn't hold any appeal nor interest.

IMHO your best way forward is to start a dialogue with those who do visit your site, ask them what they are looking for, etc. Only then are you in a position to better provide value for your visitors. It's all to do with Marketing.
