You wrote such a big post about such obvious thing, I am just surprised how you could find so many words for explainment of the most simple way: find a topic, reply it if you know the point. That's all!
I count my own comments just like you have said, but why I still not get a Merit then?
I think other users feel the same about their posts. So, your strategy doesn't work in many cases.
I'm also surprised! I think it's already in me haha, things that are simple in my mind translates a lot when i try to speak and long thoughts becomes short. But don't worry! If you think you're making good posts i'm sure people would notice it little by little, be patient, it will soon pay off. If you think you're doing everything and still people don't notice your posts, then shake things up a bit. Maybe try doing unique, i tried to make a flow chart about this post but i don't have the time to do so, try those things, be yourself, be unique.
This strategy is not full-proof this is just what i do, i don't think there's anything special about this. I am only paying forward. But it would be awesome for me if i could help others in little ways like this.
Thank you for sparing your time with me. Hope you can gain merits soon!
