Yeah, and I don't think its counter-signalling either. Successful authors are likely to have people actively promoting their work for them; the one thing others can't do for them is write (unless they're willing to have other people perform the work they are known for).
It's seems to be hard for people to imagine there are more channels than Twitter. They are on twitter, everybody they know is on twitter, and by that they judge everything.
And people on Twitter vastly overestimate Twitter's importance. That some people think it's a "public town square" is just laughable. It's the trash-laden alley behind an Arby's, at best.
