Mastodon (https://mastodon.social/about) is a fantastic new open source, decentralized, and federated social network. People can install it on their own servers, and users who are part of the community on that specific server can interact with anyone, regardless of what server they are on. You can @mention people in different networks, publicly or privately.
It is and incredibly important project, and will be a major step in the right direction to curb censorship, regain control of our data, and solidify free speech on the internet.
The convenience of having it in a One-Click Install on DigitalOcean would be very nice for anyone wanting to make their own community. The more instances, the better!
