So, am I understanding this correctly? Hivemind will provide a framework to build communities? Are these communities similar to how Reddit is structured?

Will these be built within steemit.com? Or are these individual communities to be built on their own domains with their own servers?

I'm a bit confused on how this will function. And also, this is all written in Python and thus Python can be used to build these communities? If so, I'm in! I love Python haha.
