Hi, @ crypto.piotr is really the best or only way to connect with steemit users, since otherwise it would be using the social networks that each person posts in their posts, I do not think there is another way to interact with a user . Comments are more complicated in my opinion because if the user does not post frequently, you can not communicate with them.
I used Google translator
Thank you @suanky for sharing your opinion with me.
Yours, Piotr
