shein — Actually in the past they did publicize it. When the “Hearts of Gold” serial ended somewhat abruptly they ran a whole column discussing the various reactions pro and con they were getting, and why they decided to end it.
Riva’s last serial “Shattered Glass” changed direction very sharply in the middle (the main character’s emunah issues instead became OCD, and the story shifted to focus on the wife’s relationship with her mother-in-law). There, too, they wrote a follow up explaining that they made certain decisions and changes on the advice of Daas Torah.
At the end of this story there is a line at the bottom saying that they would like to hear people’s opinions on the story, so I am guessing they are planning to do a follow up article on this one as well.
