It's because your comment didn't really add anything to the conversation. I didn't down vote you by the way, but HN frowns on such comments. In this instance though, when someone is showing the community their work, I feel it's a bit unfair to expect everyone who comments to have detailed and constructive feedback. Some people just want to say "awesome!" and I suspect the people submitting their work also want to hear that. Alas, it's a shortcoming. Perhaps up votes are the way to say "awesome".
