I can read the JavaScript I wrote months or years ago with very little effort. The language is fairly trivial, and the big gotchas have been mostly addressed by es6 and avoiding type coercion. I have limited time to dick around on personal projects and I mostly wrote Python and JS for a living, so having a familiar syntax means the difference between spending my time building cool stuff versus spending my time trying to remember how to read paren soup.
The other factors are cultural - so much of the clojure ecosystem is badly documented, or not at all. Sure, I can go and read your code to figure out what it does. But that comes back to the limited time argument, unless I'm paid for it, I'd rather write stuff in a language with a culture of proper documentation. For a recent example that does an outstanding job, see Elixir.
Finally, the ecosystem just feels... abandoned? Like walking through a ghost town. A lot of things on GitHub look incredible, but if there's no commits in the past 3 years I'm not inclined to invest time in it. I know the common argument about them being finished, and I don't buy it - non-trivial code rarely is.
