Another great article @fycee! I think the whole concept of engagement really should be underlined, and you speak to it very well here. We all have a voice and people love to get feedback! It is such a simple way to play an active role in the process of community building, and that is what a decentralized media platform is all about, building community!
People love getting feedback, being challenged, engaging in discussion. Your comments may take the discussion in a entirely new, thoughtful direction! This is important, it helps everyone to grow, to learn to expand the community's knowledge. The comments may help to grow a new project here on SteemIt, or to launch a new forum in Discord or elsewhere.
Several times now I've provided lengthy and thoughtful comments on posts and, to my surprise, a big fish dropped by and dropped $5/$6 on it. This does happen, but only if you engage :)
