This weekend, meeting a lot of people, I noticed how hard it is for us to communicate and organize stuff. Some have Instagram, some have X, both are shitty places not designed for group conversation. Some have Discord, some have WhatsApp, some don't use the phone, some have no social media, and everything requires you to either provide an email or phone number, create an account, etc, so I thought maybe it would be easier to have something like an IRC room, but it's been more than 20 years since I last touched IRC and I'm sure there must be newer alternatives around.

Main functionality I'm looking for is casualness (no acc needed) and stored live chat. The ability to pin stuff would be great, maybe create sub rooms and have private chat as well. Do you guys know anything like that?
