As you say, if Clojure's success helps Racket adoption, then I have no complaints at all. It would be great if people used both Racket and Clojure, one for (almost) seamless interop with C and custom DSLs, the other for interop with Java and concurrency - for example.
I still have hope and believe that Racket will become a successful language. I love Racket and prefer it to Clojure, that's true, but I really hope for Clojure's success too. As I said, they're both Lisps, and having even only one of them "succeed" (in terms of mainstream adoption, they're greatly successful as it is already in their niches) will make me happy. I will be a bit more happy if the one to succeed will be Racket, but I will be overcome with joy when they succeed both. :)
My own hope is that Clojure will open many more eyes to Lispy ways (including reducing paren-phobia) --- and then many of those people will go on to discover and love Racket, too. Indeed already I see people who seem to appreciate and use both Clojure and Racket. I expect that will increase.
