I’m looking for a federated social media platform that allows for easy topic-based following and blocking, similar to how you can follow or block hashtags on Twitter. On Lemmy, you can follow communities, but there are so many that it becomes overwhelming. I want a platform where I can see or block everything related to a specific tag, and also view only the most popular posts about that topic, similar to how Lemmy communities work. Mastodon, for example, only shows the latest posts, which isn’t ideal for trending content. I don’t want a chat-like experience; I want to quickly see what’s trending about a topic or what’s trending in general, while being able to block a few specific topics. Ideally, I wouldn’t have to spend hours curating a list of communities or followed users. Does anyone know of a platform that fits these criteria?
PieFed does that. See https://piefed.social/feeds which are basically collections of Lemmy communities that you can join or leave with 1 click.
You would love kbin.social.
It combined posts from Lemmy and Mastodon, allowing to browse and sort both of these like on Reddit. Mastodon toots were matched to respective magazines (like Lemmy/Piefed communities) based on their hashtags. And multireddit-like feature (called Collections there, and recently reimplemented in federated form by PieFed as Feeds) allowed any user to combine several magazines, Lemmy communities and Guppe groups in a single view.
All of these has been inherited by Mbin (a /kbin fork), outside of Collections/Feeds.
Largest instances are https://fedia.io and https://kbin.earth. There are much smaller, than flagship /kbin instance have been, though, so both will be aware of less posts…
aren’t the communities on Lemmy basically topics? why would that be overwhelming, you can easily select what you want?
Piefed maybe?
You don’t need a “platform”, you need a Fediverse indexer + search engine.
Mastodon lets you follow and block hashtags. That’s how I got my feed going when I started.
OP wants to sort posts by popularity and unfortunately Mastodon does not allow that :( Trending posts exist but only instance-wide
pumpkindrama@reddthat.com NodeBB supports topic based following, because it’s a forum and that’s literally how it was done way back then.
You can follow tags as well.
