You're wrong.

Your event sounds like a great event and is likely to be interesting to HN readers. That's fantastic! Make a post and have it voted up. The issue I see is that your comment is completely unrelated to the post except for the fact that they both happen to be conferences. There is no comparison to the posted conference, likely, because it would be a difficult comparison. The two events have different topics, currency, culture, and locale. Your post is clearly intended solely to generate interest in your event.

I don't have the ability to downvote but, I would likely have done so with the opportunity. This story is sliding off the front page so, no need to delete it now.
