Anecdotally this isn't true. The only time I have heard anything about Stephen King in the past few years has been in relation to a tweet he has made.
I think this is true for many significant accounts on the platform: I'm not going to read their blog or watch their Youtube video, but I'll probably see someone resharing a tweet they have made, whether on Reddit, HN, a news website etc.
Which is where I see the huge value in Twitter: a mainstream platform designed to present content in bite-sizes, appropriate for discussion or resharing. Twitter is a reach multiplier for many accounts for this reason.
