I’m excited about this because it’s about Plan 9 but I have no idea what it is or why I should be excited. Please tell me more.

I read the description but I’m not sure if it’s a time sharing system on plan 9 that the public can log into or another internet or... something else.

It's a collaborative environment build from 9p services. If you add the scripts to use it to your plan 9 machine/vm (or use the ANTS iso images), it will create a grid workspace with a chat, shared filesystems, ability to send links and images and documents to other connected users, and access to a registry for adding your own services if you choose. It currently has a small user community but it seems people are finding it fun and useful.
