Is there any open source blog-hosting platform?
By that I don't mean something like Ghost or Wordpress, which I can deploy and use for a single blog, but something like the "as a service" version of those, where I can create user and then. in turn, allow them to create their own blogs.
I want to use this platform as the basis for another project, not quite in this way, but finding something like this open-source would be a great starting point and save me weeks of work.
It's not open source, but Mighty Networks is a social network-as-a-service that allows you to create your own social network, on which your users can post or comment.
See Mighty Communities for example.
Try Mastodon.
It's basically Twitter, but free as in freedom, open source, and distributed. Word counts and other rules are set by the instance owner. Here's a list of servers/instances.
PS: "As a service" is a very bad moniker for this kind of thing. As a service software usually refer to something that only one website runs, instead of something you're free to download redist and run on your own. Richard Stallman even wrote an essay against it.
