I’ve not followed any writers on Instagram other than Jo and John Langan (and you if you’re on there) so I can’t comment on that too much.Fair point, but we shouldn't be in a situation where eccentric personality, real, fake or exaggerated, is the main selling point of someone's career, or where people see that as vital (or especially necessary?) to their success. It should be perfectly possible to be a complete recluse (which I'm not, by the way) and a successful writer. Given the current interest in different psychological and personality types, that kind of carefully-managed public persona feels quite "one size fits all".

On Twitter I’ve been removing writers from my ‘following’ category. Whilst I can live with the need to platform I don’t tolerate those authors who do the whole meme or gif train thing. Or that ‘what’s your MC’s favourite colour?’ Or ‘is there a dog in your wip?’ They go straight to ‘unfollowed’
