Yeah, the main difference is that Clojure docstrings are available at runtime, so it's easiest just to query a running instance; you don't need to switch to a browser to do that kind of thing.
There's a place for API reference pages, but considering that most tools to generate it require evaling the code in question, a third-party hosting service would have to implement some fancy sandboxing and wouldn't really offer much over GitHub Pages since it's just static HTML.
But I don't think when people complain about documentation that they're complaining about API reference. I suspect people want accessible tutorial-style prose and introductions. But maybe next year's survey could distinguish between the two.
