The comparisons are all to large content management systems. However this seems like a better fit for static site generators. Would it be better to compare to Jekyll, Hugo, etc?
Sure, serving static files will always be the fastest, but this is for people looking for a service like Medium, or Blogger, where there's no need to handle anything locally.
to be clear, you don't _need_ to do anything locally. It's possible to use static blogs without touching your site and there are lots of competing tools out there that will give you a web front end to your static blog.
For example. I use Hugo, with Forestry.io and don't have to touch my filesystem (or even my personal computer) to blog. I just go to a web page like all the CMS blogs.
I'm self-hosting rather than using something like netifly so the setup was a bit more geeky BUT it's totally doable and doesn't have to be tooo geeky.
