Unfortunately, you're the victim of some bad timing. Your submission's title makes it seem like yet
another complaint about being downvoted, at a time when many of us are tired of seeing these things and will knee-jerkedly downvote the author / upvote sentiments against. The submission text is fairly vague and doesn't clearly dispel the notion that this is yet another complaint thread, rather than an advertisement for a startup.
A better title would have been, "Are you sick of being downvoted for having a different opinion? Try ______." Ideally, this would have been a direct link to your site. At a minimum, the URL for it should have been included in the submission text. Having us click through to your user profile == bad usability!
That said, the blame does not fall squarely on your shoulders. There's some definite mob mentality going on here that is embarrassing for a community supposedly composed of free-thinking hacker-entrepreneurs.
