Summary of Meta Threads (currently updated)

On July 6, 2023, meta released an application called Threads.
There are various press releases and various information, so I created an article to collect accurate information.
If you have any suggestions or new information, please let us know in the comments.

If possible, I would like to introduce official statements, etc., but news sites that have been heavily SEO-optimized stand out, so if you can find the source, I would appreciate it if you could share it.
We will update the content as we learn more.

What are Threads?

To create a positive and creative space where users can express their ideas, Threads takes advantage of Instagram's strengths and adds text sharing.

That's what I'm talking about.
I think that the "strength of instagram" is visual content such as photos and images, but you can
mention (comment) this photo or spread it yourself (retweet / quote retweet on Twitter). I wonder if I'll be able to do it It's a feeling.
If you look at the official page, it seems that you can post even just a comment, so I think that it is a service that is completely conscious of twitter as it is said on the street.

SNS in the web3 era

Threads will soon support ActivityPub, an open social networking protocol built by the World Wide Web Consortium (W3C). This allows interoperability with other apps that support the ActivityPub protocol, such as Mastodon and WordPress, opening up new types of connections not possible with most social apps.

Meta has been planning a decentralized SNS called "P92" for some time.
Threads seems to be compatible with "ActivityPub", so I wonder if the identity of P92 is Threads? I think.
By adopting these protocols, Threads will be able to view, mention, and spread Mastodon data, and it will be possible to link with servers (instances) that you have set up in-house.
By sending content from a specific instance, it is possible to state clearly that it is an official statement from Company A.
At present, Twitter treats the acquisition of an authenticated account as official, but since it is a specification that can be acquired by paying money, it may lead to the solution of such problems.

About ActivityPub

The ActivityPub protocol is a decentralized social networking protocol based upon the [ActivityStreams] 2.0 data format. It provides a client to server API for creating, updating and deleting content, as well as a federated server to server API for delivering notifications and content.

The ActivityPub protocol is a decentralized social networking protocol based on the [ActivityStreams] 2.0 data format.
Provides APIs for creating, updating, and deleting content from clients to servers, and APIs for delivering notifications and content from federated servers to servers.

Simply put,

you can use the service by exchanging json such as {userid:xxxx-xxx-xxx,article:yyyyyyyy} between servers to take over user information.
The article of this person seems to be helpful for the specification of ActivityPub.
