Friend of the Retreat Jon del Arroz attended the #20BooksTo50K conference, and while he made the most of his time there the group itself didn't just have a stupid excuse to virtue signal and collude to cancel wrongthinkers; this isn't an OldPub group. This is NewPub, the folks living the return of the Pulp business model, and making a killing doing so in ways that OldPub authors--with few exceptions--wish they could match. These folks, especially the Mil-SF and Space Opera cliques (which heavily overlap), are whom I look up to and learn from- not OldPub.
And you can too. Below is the entire 2019 Conference playlist. Put the games and shows on the backburner and watch this instead if you want your writing to earn you more than some fun money in your change pocket. The Amazon data analysis panel alone is worth your time, regardless of what you write or how you approach it- and you OldPub guys getting the stick end should be paying attention because this is where you're going to go once OldPub pushes you out.
