Interesting, I hadn't heard of chachi before. TG is really one of the last apps I still hesitate to get rid of since so much of the LN community is still present there among various groups.
now that you've experienced the micro-blogging style of Twitter alternative apps on nostr, here are several more apps to help you see what's possible with the "Other Stuff" from around the ecosystem:
Highlighter - A Substack alternative https://highlighter.com
Chachi - A Telegram alternative https://chachi.chat
Flotilla - A Discord alternative https://flotilla.social
Olas - An Instagram alternative https://olas.app
Zap.stream - A Twitch alternative https://zap.stream
Nests - A Clubhouse alternative https://nostrnests.com
Need MOAR? i've only listed a few above. check out https://nostrapps.com for a list of many of the apps across the nostr ecosystem.

hopefully sometime this year a lot of these Lightning groups migrate over to Chachi or Flotilla. they're both very similar that meets different community needs.
Transitioning to some other medium is always tough. Was hard enough getting friends and fam over to signal, let alone the various communities over to something like Chachi or Flotilla. I guess I'll try them out for a while and just spread the word slowly. Plebnet's a big one but maybe a good start.
