There's been quite a bit of...unsettlement (totally a word) regarding the news that Discord has a new CEO and the company is going public (typically a sign of things going shittier than before).
I'd just like to re-post this which I shared some time ago, if you'll indulge me in my rare post which isn't a Steam Deck / Gaming News # post - a rarity for me.
In the end, this is not the be-all-and-end-all alternative, it won't be for everyone. Matrix exists of course. But this is a nice place. And I thought considering recent events I'd recommend it regardless!
Following is just a copy of what I posted last time. It's mostly Linux chat, gaming, handhelds (like the Steam Deck), movies and...general chats. Anyway, here's the post:
So...this one is a bit left-of-field.
A friend of mine (Gardiner Bryant of YouTube - who reports on Linux and the Steam Deck) has started a Revolt server.
What is Revolt?
It's kinda like a FOSS alternative to Discord. You'll see the layout is almost a direct copy, and it's far less polished...but then again you haven't got the downsides of Discord's constant upselling either:
Why is this relevant?
...I can hear you ask? Well, so far its just a few developers and creators in there, but I thought of all spaces...maybe those very devs and creators whose work you use and watch...well it might be nice to join in there?
My personal friends who are in here so far are:
-
imLinguin whose GitHub is here - but you may know most as a developer of Heroic Games Launcher
-
Lazorne whose project is RetroDECK - my personal fav emulation option for the Steam Deck
-
Eben Bruyns whose GitHub is here - but you may know best as the dev of Junk-Store
-
Kyle Gospo whose project is Bazzite
-
Gardiner himself, of course whose YouTube link is here,
What is the damn link to the damn server, woman?
I mean, you will have to make an account on Revolt, but it might be interesting to some here. You're all very welcome!

For the record RetroDECK also got Matrix instance as well. But Revolt have so far been more active then Matrix (even tho we had that one for a long time).
But I do agree with that Discord is not a replacement for forums. You should not use Discord as your primary information hub.
For us our own wiki is the master of information. If something relevant is said in Revolt / Discord / Matrix we will add it to the wiki, people should not need to register various accounts to access the information.
Github is also where we handle "real" issues, while Discord / Matrix / Revolt is helpful for community members helping other with minor issues or general banter.
One reason why forums died out was the need for direct engagement and a sense of active community belonging, that they simply did not offer.
We also did not create all of these spaces from the beginning. Some community members did it, like the subreddit. Then you have a choice either you create it and own it, or a fan will.
