Is there not federated WordPress?
Edit: Okay its done, not pretty but I like it and it will do for now. I mostly want it as a guide to send people to my different social media sites and my Payreon where I have decided to post the webcomic.

I think this is a good suggestion. As a single user, you could still theme it while also providing cross-posting of other artists you like. Additionally, your network would act as a “web ring” of sorts.
