Content warning:ATProto Rambling
I've definitely softened my stance on ATProto a lot, but I still don't think it's a decent replacement for ActivtyPub like a lot of people are billing it to be. 
ActivityPub does a better job of creating organic, decentralized social webs, while ATProto feels like it's more of a social network workbench for creating more monolithic networks instead of social webs. Decentralized moderation and community-run networks don't really seem to be a core goal like it is on ActivityPub, and I kind of doubt it'll ever really be a thing with ATProto like it is on Fedi.
I do like how ATProto uses websockets to fire data around from PDS's to AppViews instead of having to mirror everyone's data. Fedi is pretty wasteful in that regard (granted ATProto's approach wouldn't work here). I also do like the concept of the nomadic IDs/DIDs in theory, but in practice the only useful DID system is DID:PLC, which is centralized and kind of defeats the point of a decentralized protocol.

One of my goals with #ONI the single user #ActivityPub profile is for it to be dead simple to install and run.
Today I played with the serverless provider Koyeb, as I have an interview with them tomorrow, and managed to set up a running example in under 10m:

The vision of #ActivityPub AFAIK is that social media servers would be as ubiquitous as websites and email servers and just as independent. That's not the model of #bluesky relays or any other social media model I'm aware of.
Am I wrong to think that matters in regards to free speech and #DemocracyOfReach? Is it somehow unworkable? Or are there other goals that people think matter more? What am I missing? #SocialWeb

Frequently /me [from DE] thinks about #Datensparsamkeit
The officially best [en] explainer is
https://martinfowler.com/bliki/Datensparsamkeit.html
@mfowler
I became a Carteret Islands person once.
Looking at my shell neclace.
My wish for christmas is that you read it and carefully think about all the things you publish in terms of accessibility but also formats and size.
An example:
For @clemensg I did the yearly #ActivityPub #Atlas -
it comes with millions and millions of geohashed places for OSM, wikidata, official sources and, well openaddresses [.io]
They publish primarily in texts with lines of geojson.
The whole planet is about 46 GB … … …
An exmple:
DE in this "format" is about 3.2 GB
DE in CSV would be maybe 1.5 GB
If we normalize and publish it compressed, it is [incl geohashes] about 800MB.
If we now compress the geohashes, expanding it clientside the
3.2 GB becomes 
250 MB …
Maybe we can't save tons of powerplants like banning bitcoin would.
But together we can save lots of energy.
#geojson 💣

The codeberg issue is kind of still an ugly scratch pad rn. The thing awaits a follow-up where stuff is more organized and easier to drill down into. Proper docs eventually.
A first step may be to name the discrete and granular building blocks that one should focus on when starting out on an #ActivityPub client-to-server adventure quest. Give them consistent names. And then to map all the various projects to that as a MDN-like who-supports-what table.

I wish I had #fediverse (#mastodon #pleroma #akkoma #friendica #hubzilla #iceshrimp #snac #lemmy #mbin #kbin #piefed ) #client , I mean like #ELK #lmst #pl-fe #phanpy #tooty #sengi #pinafore #halcyon . That would allow me to sort my subscription feed & browse sorted feed, to see ONLY relevant posts (on topic updates follow-up's?).
Well, the mastodon feature of "LISTS" tries something similiar by allowing to make a sorted list of people\subscription, sorted by your custom category/topic. But it doesn't include #tags. Each #tag must be browsed separately, individually, manually, and there is no feature of list of tags in mastodon.
Lemmy, mbin, kbin, piefed and other #reddit #forum like #activitypub implementations allow you to have topics-threads, but each thread does not replicate very well across multiple servers/instances. Can't be easely crossposted ( by pinging multiple category-bots). And doesn't replicate & easily-searchable as classic mastodon #tags.
Other things I don't like:
- twitter like reposts. they make you feel you subscribed not to the original "reposter" friend, but to "reposted content" that you never subscribed for. the #f2f p2p architecture of #scuttlebot (#scuttlebutt) kinda eliminates that, they don't have nor show reposts. you see there only original posts, original content, of friends you follow. Kinda helps to slow down the mind from informational overflow. You can opt out to see posts of friend's friends, if you want more. Tags are also supported there.
- threads consist only of information aggretator url sharing in reddit like clones. Without having OP OC like in bbs|AgoraRoad , they just silo you to clickbait to other web sites.

This is something I am eager to test in a new #ActivityPub implementation.

For people interested in #ActivityPub #C2S (client to server), the #GoActivityPub services have gained the ability to dynamically register OAuth2 clients based on RFC7591.
The easiest to test is the ONI project that can be directly run without much setup: https://git.sr.ht/~mariusor/oni
