The problem with Kind 1 is that a lot of people in other timezones won't read it.
I've tried Kind-29 and managed to lock myself out of my own community lol. Also, I haven't felt a lot of enthusiasm from other folks to play with NIP-29. 0xChat Signal like LMS stuff sounds exciting. nostr:nprofile1qqsf03c2gsmx5ef4c9zmxvlew04gdh7u94afnknp33qvv3c94kvwxgspr9mhxue69uhkscnj9e3k7unpvdkx2tnnda3kjctv9uq32amnwvaz7tmjv4kxz7fwv3sk6atn9e5k7tcppemhxue69uhkummn9ekx7mp0g4rts7 is also working on a Slack / Discord like thing with Flotilla, but it's still at early stages.
I'm happy with whatever tech you folks pick, Nostr or otherwise (although I would prefer Signal to Telegram and XMPP, IRC or Matrix to both of them). But lets start creating those groups/ channels somehow. It has been hard to keep up with what all of you folks are up to.
