"The fediverse (a portmanteau of "federation" and "universe") is an ensemble of federated (i.e. interconnected) servers that are used for web publishing (i.e. social networking, microblogging, blogging, or websites) and file hosting, which, while independently hosted, can communicate with each other.
On different servers (technically instances), users can create so-called identities. These identities can communicate across the boundaries of the instances because the software running on the servers supports one or more communication protocols that follow an open standard. As identities on the fediverse, users can post text and other media, or follow posts by other identities. In some cases, users can show or share data (video, audio, text, and other files) publicly or to a selected group of identities, and allow other identities to edit other users' data (such as a calendar or an address book). A key distinguishing feature of the fediverse is decentralization. There is no central authority that controls or determines what is acceptable as each instance is independent." - Wikipedia
A lot of these platforms try to implement the Decentralized, Open Social Networking Protocol called ActivityPub.
"It provides a client/server API for creating, updating, and deleting content, as well as a federated server-to-server API for delivering notifications and content" - Wikipedia. This allows me on the mastodon instance infosec.exchange, to interact with someone on Meta's threads, someone on another mastodon, or look at [email protected], for example. This way, we can traverse entire social medias without switching accounts!
While these are good benefits, there are always challenges, like:
!!!!! Every major platform has a join-platform style page, which extensively documents the process, in an easy to understand way.
There will be many more, to discuss about federated communities or alternatives, hop onto our matrix room! As for self hosting, it is possible and even encouraged! These join style pages often have a section for self-hosting
Big tech hates this one easy trick: Just use it!
One of the responses I've heard goes "but nobody uses it!"... You using it especially as a protest tool, shows others that there are users on the platform, and convinces them to move. Even a single person encouraged is worth something, when it comes to an open platform.
Word of mouth and generally talking about it online is a powerful tool!
