Writing here for me is like making an open diary that everyone could read and share their thoughts with, as well as something that I could go back to maybe 20, 50 years from now, and might be still available even when I'm gone. I will be lying to say that rewards do not matter to me, but there are also stuff that I wrote because I have an opinion on a topic or had an experience that I want to share. Regardless of the reward, I put the same effort into what I write, so that I don't embarrass my future self when I read my previous posts.
