There are many
#Friendica fans, and for good reason. Once you get past the learning curve from the difficult UI, you get to appreciate the extra benefits of built-in
#Bluesky,
#Lemmy/#Piefed/#MBIN,
#Tumblr, and
#RSS feed integration. It also has
#Diasporia integration and some other protocol integrations. Of course, it's also a
#Mastodon alternative.
Nobody ever mentions Friendica as being a
#Threadiverse app, but it has Groups, which is built-in Threadiverse capability. If you follow a Community on Lemmy/Piefed/MBIN, for example, it gets categorized as a group and is placed into a separate section for the groups you are part of. Then you can read and post in the Group (Community/Magazine) just like you would on a Threadiverse application. You can also create public and private groups.
And there is no need to use a Bluesky bridge if the Friendica instance you are on has the integration turned on.
Here's an excellent 5-minute video showing Friendica created by
