Yes you will increase your reputation. That is exactly the point you will learn. You don't ever have to make a post (unless you like to) and you can still earn respect, make friends, earn money, and build your reputation. I would say that I have earned 10x the money I have made from my comments and not from my posts.
I highly recommend you build your skills at commenting (sincere and thoughtful and pertinent)... And if you are funny and sympathetic when they apply, then that is good too. There is so much amazing things out there, you just need to venture into other people's posts and strike up a converstation.
And I'm glad you're in both ways. And I'm excited for you to see how this works out. There is a whole ecosystem out there than you can repeat over and over and have fun doing it too.
I'm happy you asked that question because one day I want to use you as an example of how to succeed!
