If you're talking about work, then community building is really important to gain trust and improve communication. I've been working on https://thebutterapp.com/ exactly for this. We're still in Beta but we're ready to roll out!
Hey Vinicius, that's a good question, you know! ππ
I think the best platform to build a community is where your target audience already lives.
I decided to start my Russian micro-community for startup founders and makers. I'm a founder and maker too. And we are living in Telegram and Facebook. I started to write posts about startups on my telegram channel and on my Facebook. And now there is my micro-community of founders and makers with 1000+ subscribers.
People love the platform that they use every day. If your audience loves Slack β that's the best platform for you.
Slack is great because of all the features you can get - as well as channels for navigation. There are plenty slack communities with thousands of users.
VoicePing is our community right now. We recently launched VoicePing is an all-in-one application, that provides you with voice/video calls, a workspace, and time tracking in one package β all of these are outright necessities in most 100% remote organizations! https://voice-ping.com/en/ Do let me know if you have any feedback?
