I want a single feed that I can customize and preferably weight based on how important I think something is.
The perfect solution would support Lemmy, RSS, Mastodon and maybe even Bluesky. And would allow me to increase the visibility of certain content. For instance a specific RSS feed
As a workaround there are Lemmy servers (don’t know which one off the top of my head) that basically mirror RSS feeds to their communities. And with Mastodon you should be able to follow them.
Pretty sure it’s all of them. It’s a built-in feature.
