Congratulations! You've found a test/staging instance. This instance isn't likely to be the primary domain for this software. (How domains work is complicated. See the technical documentation when it's available.)
This is experimental fedi software under active development.
Feel free to poke around, and check back here for a link to the git repo full of AGPLv3'd code.
If you're seeing this because the software is doing something weird, please excuse any bugs; I'm still working out some problems in federation. Great care has been taken to keep it from overloading anything.
Kept you waiting, huh?
