GNU social VS Friendica

GnuSocial - Oldest microblogging platform.

You might want to look into some of the Facebook-like open-source social networking programs like Friendica, Hubzilla, Libervia, or GNU Social

I think that Friendi.ca is the fediverse equivalent of FB, in the same way that Mastodon is to twitter. https://friendi.ca

In addition to what has been said, you can also use Friendica, another great decentralized alternative (server list). It supports RSS, along with being a regular social network.

facebook being whatever it is would be friendi.ca

Given the similarity to FB, what's the advantage over Friendica or Hubzilla? Both support federation with other servers and can be run as a closed community too.

The Fediverse has many different types of platforms, including video hosting on Peertube or Friendica which is similar to Facebook. Mastodon got the most publicity, but it only uses a fraction of the possibilities that ActivityPub offers.

Friendica is powerful, but it's also very complex. If your primary goal for the server is simple discussions about your website, Friendica might be more than you need.

Are there any plans to set up some kind of presence in the decentralized fediverse (e.g. on Mastodon) or a community channel via the Matrix protocol? Services like Mastodon or Friendica are federated social networks licensed under FLOSS-licenses. Those "talk" to each other using open protocols like "ActivityPub" and/or "DFRN". Matrix provides similar functionality compared to Discord and is free (libre) and open source as well. Basing communication on free software can be seen as a political act. ;)
