I think you just need to wait. Dang has pointed out that early posts on a new-ish story tend to be of the lowest quality. At this point, most of the shitty posts have been downvoted and the top spots have been replaced with better quality.
Granted, looks like you posted 8 hours after the story was posted, so that should be enough time.
