This is really cool. It has retro vibes of the era when the Internet was still free from the big five domination.

Those of you old enough to remember etherpeg can now see an ATproto version: https://bsky.land

I often wonder if people have forgotten that you can send information through the internet without HTTP(S)

I think it would be interesting if the file servers had read/write/list/delete permissions on files. For both groups and users. It would mean the public stuff could see your files but private projects could exist. Eg. Maybe I don't want my At Protocol version of Figma making all my drawings public. If they could be shared in a group (anyone in a list in that folder or whatever). Maybe this is coming, but would interest me way more about using applications on the atmosphere.

I didn't understand what this was until I did some more digging around. Apparently, it's a decentralized way to interact with social media. A protocol created by Bluesky which allows social networks to communicate directly. This is similar to how different email clients like Gmail and Outlook can send messages to each other.

I could see this turning into a more modern and sane usenet replacement

Blog post about this new site from February might shed some light: https://atproto.com/blog/new-site-2026

How common is it to host your own PDS? It's not really clear to me what the advantages/disadvantage are.

The summary of what this is about is: "Atproto is a big-world open social protocol. Users publish JSON records into repositories. The changestreams of those records then sync across the network to drive applications." It's too bad that information isn't on the front page. You have click "GET STARTED" and scroll down

Someone posted this article[0] earlier today and I thought it was a really good primer on AT-stuff I've been playing with my own PDS and AppView for a side project, and it's really fun and interesting. [0] - https://overreacted.io/a-social-filesystem/

I love that it embraces standoff properties for rich text markup.
