So I setup a list of maybe 30 highly active matrix rooms organized into Matrix Spaces on the QOTO Matrix server (though you can access them from any spaces enabled matrix server).
Just login to your existing matrix account on any server, or register for a free one at https://element.qoto.org (registration open to everyone). Then join any of the following spaces (make sure you turn on spaces in your config under labs first).
Please let me know if you have any rooms you'd like to suggest to be added to any of the below spaces. Also, feel free to create your own space and share it.
#QOTO_space:qoto.org - Rooms related to QOTO itself
#Fediverse_space:qoto.org - Various rooms from matrix servers that have a fediverse hosted as part of the same community.
#STEM_space:qoto.org - A collection of general topic STEM rooms like Electronics, Physics, Math, etc.
#Regional_space:qoto.org - Rooms specific to Countries, towns or regions around the world.
#Projects_space:qoto.org - Channels for various open-source projects
#linux-distros_space:qoto.org - Rooms for various linux distribtuion flavors.
