When they leave a comment on the blog, read it, maybe, but don’t respond.
If they ask a question on social media or by email, ignore it.
Don’t offer new information, say, by posting to your blog or updating your website.
Instead, disappear for weeks at a time.
If you want to compete in the business of being an author in 2016 you had better be approachable and responsive.
Or someone who is will take your readers.
And their money.
