After joining Lemmy I have been wishig on a feed of content from self hosted blogs, to display in a feed similar to Lemmy. Where we ca. Subscribe to Themes, hashtags or topics and link to self hosted blog posts or simply self hosted videos, images etc. I may be rambling or dreaming of something that really wouldn’t work but I kind of miss the Instagram kind of feed. Lemmy had effectively replaced Reddit for me but I still lack a more visual social media like IG
There’s also Friendica, it’s more often use for #blogs while Mastodon mostly used for #microblogs
You can also follow #Lemmy communities using #Friendica groups feature
