There are a few disconnected topics I intend to write about--but I don't think I'd like to here if they're all strewn together. Ideally, what I'd like to do is have something like "Modern Applications of Ancient Philosophies" or some such thing be the category, and then have individual hubs fall underneath it. However I'd also like to write about maybe different topics within the education system specifically, and so have that as a category with its own hubs as well. Is there a way to do that here? Or should I use a different site?
