How many authors are on your mental auto-buy checklist? How many are on your keeper shelf? And how long have those authors been at the heart of your reading universe?

Or, to put it crudely: there’s a limit to the number of people your brain has space for.
Dunbar’s Number has been around since the 1990s, but I came across it when I started writing fiction with an eye to publication and realized that meant I’d have to get to grips with social media.

- The next closest layer, good friends, would be about fifty people (including the first fifteen);
