I would like to discuss a new Tag `#matrix.org` for SuperUser.

## What is Matrix.org
The [Matrix.org][1] is an Open Source, decentralized, distributed, **chat protocol** to have private and group conversations. It supports easy interconnection to IRC, and server-side applications to bridge Matrix.org users to Telegram, Slack and so on.

Matrix also supports "Application Services".

## Adoption

Matrix.org has a lot of official and not-official Open Source chat clients. The most famous is probably Element.io, available on Android (also from F-Droid), iOS, and Linux desktop (also via snap) and also as web application.

It's interesting that in 2020 they received 5 million dollars of donations just from Automattic (company behind WordPress).

## Proposed description for the tag

Matrix.org is an open, decentralized, distributed protocol. In-topic questions include: usage and fix on desktop clients, or "Matrix Application Services". Off-topic questions include: specific web client (ask in WebApps); programming over this protocol (ask in StackOverflow); server-side errors on a Matrix server (ask in ServerFault); using or fixing a Matrix Android app (ask in Android).

## In-topic considerations on Stack Exchange

The [WebApps][3] network can host in-topic questions related to a very specific web-app of the Matrix protocol, like https://app.element.io/. For this case I would suggest to propose in that network a new tag `#element.io` (not to be discussed there).

The [StackOverflow][4] network can host in-topic questions about software programming related to implementations of a Matrix.org client or something like that. For this case I would suggest to propose in that network a new tag `#matrix.org` (not to be discussed there).

The [ServerFault][5] network can host in-topic questions about how to fix server-side errors related to hosting a Matrix node. For this case I would suggest to propose in that network a new tag `#matrix.org` (not to be discussed there).

The [Android][6] network can host in-topic questions about how to use or fix a particular app on your Android device related to the Matrix protocol. For this case I would suggest to propose in that network a new tag `#matrix.org` (not to be discussed there).

What do you think about?
