Thank you for the friendly advice, but to follow that advice I would have to have more time and something interesting to add. That is not always possible. That is in fact usually not possible. I did write a few articles on steemit, but mostly I treat it as an equivalent of reddit, and I do not believe it to be wrong, because that way I could share with you something interesting.
