Lemmy is a really great piece of software and i’m happy to use it but i have to say the quality of the content is really low and the way the platform is structured isn’t helping. The frontpage is filled with memes and news from third parties and most discussions are happening below stupid headlines. If i were to document a live event i have no idea were i should post.
As others said: find your favourite communities and subscribe to them. Filter your front page by subscribed subs. Block annoying communities if you ever browse by all or local.
Other than that, what content are you looking for? Niche subs? I miss out on these too and I use a self-hosted Reddit frontend for these. I do not post, so that suits my needs.
