Not every site is Hacker News. /r/node and EchoJS are two much less hectic sites where you easily can get some attention without getting run over by other projects. You managed to get people to read your blog and give feedback here, didn't you? Post to these low traffic sites first and only use HN for when you want to go full on public. But you also need to take into account that maybe people don't have the same use for your project as you might want to believe? Like I said, most projects fail and that is what drives evolution and competition.
