First files are awesome, because the file format is the API to understand the content.

You may create a file in one app, but someone else can read it using another app.

After this introduction, an everything folder for social media is the theory: the folder would include everything you've created across different social apps. In that world, a “Tumblr post” or an “Instagram follow” are social file formats.

Bluesky, Leaflet, Tangled, Semble, and Wisp are some of the new open social apps built this way.

The author then details a typical social media post in JSON format, and how to store them as files. Domain names can be used to split each social media.

Then how to store a like with identity files (and the standard DID).

An example of such architecture is available at https://pdsls.dev/at://did:plc:fpruhuo22xkm5o7ttr2ktxdo

The apps then reacts to the change made in the social filesystem.
