What is Mastodon?
Mastodon is an online, self-hosted social media, and social networking service. It allows anyone to host their own server node in the network, and its various separately operated user bases are federated across many different sites (called "instances"). These instances are connected as a federated social network, allowing users from different instances to interact with each other seamlessly. Mastodon is a part of the wider Fediverse, allowing its users to also interact with users on different open platforms that support the same protocol, such as PeerTube and Friendica.
Basically it's Twitter without all of the deplatforming, censorship and some large company owning your data. So why the lesson in federated social networks? Well, the answer is you can now try one out that's operated by the same people that brought you the Dudebro Nation forum that's been around for 10 years. By signing up you'll be able to post Twitter like posts on a private network and because it's federated you'll also have the option to make your posts public to all of the other instances around the world. You can also follow people from other instances. Give it a try at https://social.dudebronation.com and after you sign up be sure to follow email@example.com.
