the big question to answer is what makes sense to centralize vs. decentralize.
people "don't want" to visit websites these days; they want a single convenient platform. cool, so that's what this service offers.
but the underlying sources of content and information -- the tools and platforms you use to *create* content can be anything you want.
the idea is:
creators keep their choice of tool, ownership of their data, and independence (including using their own domain name), and
hanging out happens in one convenient hangout spot.
