This is why I don’t think the Lemmy platforms will really grow to Reddit size until we solve this problem. Most folks don’t want to curate their own feed when they first explore a social media platform. That usually comes later after they’ve been drawn in.
What Lemmy and kbin could really use is a set of default subscriptions that are curated by instance admins to provide the best new user experience.
For that matter, default block lists wouldn’t be so bad either
