Don't make a business out of it, at least not directly. Make an open source, federated clone, ideally with something like GNUSocial driving it - something that doesn't go down under the pressure of endless bullshit DMCA claims or investor pressure. Sell your services as a consultant maintaining it for artists who can't get the technical bits down.

We have got to quit trusting commercial entities with our culture. They are not good stewards of it.
