Have you ever made a post and receive great comments. Comments that you'll feel just deserves more than the amount from your full power upvote?
Commenting
Commenting is a crucial activity for someone starting out to engage with everyone. Heck, even the best authors are the most prolific commenters. As I pointed out in my post about the do and don't of a minnow, a good comment shows that you not only appreciate the post you've read, but you are willing to engage in a further discussion with the author in regards to the post content.
Personally, I always try to engage with every good comments someone took to write on my post. I appreciate it and the more comments I get, the happier I am. I don't mind if that someone my disagree with me. I'd rather have a healthy discussion in which I may be enlightened to new insights, rather than a low effort comment of "Nice post!".
With the recent Hard fork 19, my full powered upvote at 100% will net around 58 cents, Of course that is if i haven't voted anyone in the past few days. Not bad, considering a few weeks ago the best I can do is 3 cents.
But even then once in a while I come across such powerful comments by great people that I think even the best I can give isn't enough. Insightful, funny, heart-warming, tear-jerking, however it may be. Ones that resonates with me, touches my heart. The ones that I gave 100% upvote without a moments hesitation. And as we observed, net the most, 58 cents. I dont feel right awarding someone the theretical maximum of 58 cents when that person spent their precious time reading my content, understanding it, and take the time to reciprocate and reflect on my points and shed light to me on things related to what i talk about but may not know.
Imagine if there's just a way get that com mentor the renumeration he/she deserves.
Comment of the Day
I'd like to introduce you to Comment Of The Day. An initiative born of the ideas of 
You don't even need to actively participate. It's meant to be passive. Let me explain.
Everytime you come across a good comment, it doesn't matter if the comment is on your post or on someone else's. The only rule when it comes to selecting comments is that it can't be your own. Afterall, don't we all think we ourselves are Great? Wouldn't be just and fair now when we do that right? :P
Comment on the contest post (posted on regular intervals) your nomination, quote and link. Have everyone to take a look and see if other people agree that "hey, that's a bloody nice comment"
There's 5 slots for each contest for winners. "Champion" all the way to 5th place. Owh, and by the way if your nomination won you get a cut of the win too. So there's that.
Why should you reward your commenters
Asides from the obvious incentive (Direct power-up to you, a fast-track SP building) to nominate and vote for the best comment. There may be a few hidden benefits. For example:
Engagement
If you commented on someone's post and suddenly realized he/she nominated your comment as the best, wouldn't you love it? Rewarding your commenters in that way persuades them to come back to your future posts for more. It lets them know that you appreciate their engagement. Sure you always give full upvotes, maybe.. sometimes.. But it never hurts to go extra right?
Community
It's nice for your commenters to know that you're looking out for them. People always return favours, It might just be that in the future, your good comments will be given more attention because you've first given attention to others.
Encouraging the culture of good comments
Aren't you tired of "nice post"s? I am.. And on a particularly good day commenters like these will make me go on a hunt to find out if the account is in fact human or bots. If it's a bot that brings no value to the platform, im heading to #abuse channel over at Steem.chat. And so on the other extreme. I do my very best to reward people who takes the time to make sure their post is engaging, thought-provoking, heart-warming, ones that has a point, and a good one.
To wrap things up
A dolphin or whale vote on a comment will make someone's week. But like you and me, our votes don't count for much unfortunately... for now. Nominating good comments in CotD contest may present as a gesture of goodwill and a chance to sort of "give them a whale or dolphin vote". I assure you it feels nice. from my experience, being rewarded in that way encourages me to write better comments because i know the post writer appreciates it. Afterall, we're all about good content here.
