so excited to get this in folks' hands and to see what people build with it!
it’s been a lot of work getting here & i'm proud of where it's at
check it out, bang on it, break it, see where it doesn't work. let's make sure this is something we're all excited about & can take pride in building on

continuing to wrestle with the uri scheme for permissioned data
i'm currently leaning back towards `at://`. get in here and let me know what you think!

one benefit of the rise of ai writing is that i feel more personal liberty to let my voice come through in my writing. colloquialisms, asides, jokes, mixing of registers, etc

ayyy check it!
alex & the app crew are working on the designs for this while i'm working on the permissioned data protocol
& it all meets in the middle with ✨atmospheric communities✨ ideally operating on an ecosystem standard a la "standard.site for communities"

how do we feel about `space://`?

new data diary!
this is the most in the weeds yet, all revolving around our proposed URI structure for permissioned data. turns out you can figure out a lot about a protocol from the uri!
as always, let me know what you think :)
