Because Racket has a run-time it competes directly with Clojure, which is obviously widely popular. You can bundle the Racket runtime in your binaries but startup is slow (much slower than Gambit, for example). So for me at least, it's simple. If I don't care about startup time and just want the best ecosystem, Clojure is a no brainer. If I do care about startup, you have to pick one of the Lisps, probably either SBCL or Clozure.
