This is a group of public toots with #thatbrownstuff. You can play with this if you add an account on any Mastodon instantiation.
What is Mastodon?
Mastodon is a "FOSS" social sharing hub. A multi-host substitution for capitalistic platforms, it avoids risking a particular company monopolizing your communication. Pick a host that you trust — you can still talk with all hosts running Mastadon. Any individual can run a Mastodon instantiation and join in this social hub in a jiffy.
Built for actual communication
With 500 symbols at your disposal and support for granular posts and tricky topic warnings, you can chat how you want to.
For a human, not a product
Mastodon is not a for-profit tool. No ads, no data mining, no DRM. Nobody is a singular authority.
Always in proximity
Apps for iOS, Android, and various platforms thanks to an API allow you to follow up with your contacts in any spot.
A human approach
By looking at failings in prior social toos, Mastodon aims to put morality as top priority to combat misapplications of social computing.
