This topic was split from another topic. I split the topic to keep the discord topic in a separate thread.
Quoting relevant section about Discord in my initial reply in that topic -
On discord too we have one or two developers lurking and answering stuff, although it is not official. Members from Krita team try to be in most community spaces and answer things whenever they see anything. Being official or not doesn’t matter, what matters is the engagement and that is happening there, so it is doing a good job. If there is any need for official help someone from the team steps up and answers or guides the user to the correct place for answers.
Krita’s community is built around volunteers who step up and do the job of helping others and building the community, due to developers being already overloaded by work they can’t be present or manage every channel. And it is also not good to force a dev or team member to be on a channel to maintain it. it is their choice. For example some developers may close their Reddit account and soon no one from the official team might be there. That doesn’t mean volunteers can’t take over and handle it.
With the growing number of Krita users these kinds of community will be springing up a lot, there will be many forums, chatrooms etc. it is best left to the community to shape and build it. Who knows may be in future we would also have a Krita User Group meet up event in various parts of the world.
Regarding making discord an official channel for communication, the most important reason against it is that it is closed source, and it is not even possible to self-host it. What happens when discord takes control and shuts down your official channel? IRC and matrix chatroom is the official chat channel. For those who like discord there is the Krita channel, and it is a good place, people help each other and solve issues. What would make it any different with the “official” tag?
In the official chatroom on IRC / matrix we hold weekly meetings and other stuff and for now the developers are comfortable with it. Apart from the meetings and development discussions by core developers on it, it is no different from the discord channel. People join ask questions chat share artworks etc. It is just a matter of choice, discord is the new hype today, tomorrow it would be something else. But IRC is there from the beginning and probably will there for years, so it makes sense to stay in a stable place.
