@jake_gutstein Oh I missed the discussion then. Personally I'd prefer twitter when it is someone I've never interacted with. But if I know the person from somewhere - Product hunt for instance, I would be happy to connect with them on Linkedin.
Discord communities of products embracing #buildinpublic are 🔥
I visit them every now and then, see and participate in a community of people (not just the team) coming together to build something together.
The platform isn't as important as the on-line community itself. I've seen some good ones and really bad ones on all these platforms and many outside the "centralized" social platforms. It's all about how vibrant/valuable and managed they are in the platform that is hosting them.
