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.
thinking about how this works with the open web, I imagine your Remark.as profile could plug into other blogging and photo-sharing backends, like @pixelfed or any photo-sharing silos that offer enough open data access
in the fediverse, I'm not sure if this means creating a simple frontend, or if Remark.as implements the #ActivityPub client-to-server protocol, and acts as the client 🤔
