One possibility would be to switch from Libera.chat to Open and Free Technology Community (OFTC), or at least also have a room there, since there seems to be a working Matrix-OFTC bridge (Bridged Networks - Matrix IRC Bridge). (First mentioned here: Future of the weekly Ansible Community Meeting - #9 by felixfontein)
As @shertel pointed out below that post this again increases fragmentation of the community. But on the other hand we’d have a bridge back between IRC and Matrix. Maybe just having one channel on OFTC (instead of the pletora of channels/rooms that we have on Libera and Matrix) would already improve the situation, in particular for the community meeting (whose future has its own topic: Future of the weekly Ansible Community Meeting).
What do others think about this?
