The most important post for me till now would be this one! Thank you so much ma'am!
Your points are absolutely stunning because for almost every person the comments are the start about their interaction with other steemit users and followes, and if you build a positive image of yourself then you can get alot from that person in return too like an important upvote or some rewards.
Your contents of the blog seems complete and reliable but I would add a point that positive feedback has an important role in building your social interactions with others and if your comments show some positive attitude then you will surely get a positive response in return from that person. Concisely, positivity is the main point of a feedback.
BTW this blog is really informative and helpful for starters like me so Thank you for this again!
