Reading as a habit is very good but, in agreement with your comment, it has disappeared. Simple reading, digital books, audiobooks, little elaboration of the texts, little time from us, etc. have conspired against the good habit of reading the printed page.
In this regard I can say that SN helps us since we do not only see the most important news or events, we have to prepare ourselves well to issue our comment, which implies research (reading) and then developing good writing. In this sense SN is contributing to the good habit of reading, even if it is digital, research and the development of writing.
Let us not lose hope, let us adapt our routine to the changes, if there is a good printed book, do not stop reading it, but above all, let us not let mediocrity consume us.
