Thanks for the answer :)) I'm friends with people in Steemit. The best option for me is comments. People often read my comments, answer me, we communicate and become friends. In Steemit there are topics of articles that I understand well and can comment. This makes me happy. However, as before, I do not understand everything in Steemit. And I do not know how to use a bot. Thank you for your article. I got important information :))
