Have you tried it? Are there cool communities there? looks like a new product so not sure how many people are there.

There's a community on there for people working on neural interfaces 🙂 You're right, it's still very new so there aren't many people using it right now. But the UI/UX is very nice and feels familiar (The user home page looks like a facebook messenger screen) so I'm hoping this one sticks for a long time
