True enough on utilizing psychological triggers to get people interested and involved in your post.
Just as the content of the post is important so is your branding and engagement of your commenters.
Upvoting their comment if you can will make them smile and if you give a nice comment back not just an ordinary thanks for dropping by will further enhance teh relationship building.

If you want to fly like an eagle don't hang around chickens. If you limit yourself to that first group and be afraid to engage other people not necessarily whales and dolphins if you lack teh confidence then it's hard for you to move up.
Connect, network and engahe. Increase your visibility and when someone notices you hard around or have them always comment on your post then by law of association your respect level in the community also rises.
Think of teh sun as the powerful beings and you are the moon. By the reflected radiance of the sun the moon shines.
