What is Mastodon?
Mastodon is a social network similar to
Mastodon was created by Eugen Rochko and the initial release was in March 2016. The software is now maintained by the German non-profit, Mastodon gGmbH.
All of the instances communicate together, but there is no central service that coordinates all of the servers like many other social networks. It is referred to as a decentralized network not owned or controlled by a single company or organization -- instead it is made up of instances that are run by... anyone! All nodes are independent with their own codes of conduct, terms of service, and other policies.

Mastodon is a federation of instances, the first hurdle for most users is choosing an instance. The nice thing is that this isn't a binding choice and you can transfer from any instance you choose to another whenever you want. joinmastodon.org has a list of servers that can be filtered by region or topic. If you are consumed by analysis paralysis, you can always join mastodon.social which is the canonical
Mastodon is also relatively new (compared to other social networks), so there are less tools and ecosystem built around it. However, that seems to be changing over the past few months with more attention drawn to
Mastodon after Twitter was bought by Elon Musk. Here is a continually updated list of tools for Mastodon.
