I declined an invitation to publish in an edited volume last week because the editors don’t have well-developed profiles on academia.edu or Research Gate even though they are younger than me.
I wouldn’t care about this if they were from an older generation, but youngsters? That they haven’t bothered to do something as simple as that tells me they won’t show any initiative in promoting the edited volume.
It’s one thing when everybody already knows you. But early-career academics who don’t take advantage of social media to get their name out are simply weird.
