It does take patience to "get used to it". The effort of "getting over the hump" is amply rewarded--one way is the benefit of seeing how marvelously consistent and predictable the notation proves to be. IOW it's a great simplifier, allowing humans to mentally read, parse and understand Lisp code.
To me the great genius of Lisps is shown by the experience of looking at work I'd done months or years ago. Stuff I'd written before in C would often be obscure to me later, especially when I hadn't made enough comments to "explain" what the code was doing.
In contrast, it's much easier to understand my old Scheme programs, often just minutes of review will do it. Sure, I'm talented at making things convoluted, it's just harder for me to do that with Scheme, and no doubt that's true for Lisps in general.
I've looked at Clojure a bit, my impression is it's syntax is more complicated than Scheme. At least there are enough differences that it would take some effortful study to become fluent in Clojure. Not a criticism of the language, but suggests making the transition isn't trivial. Perhaps that applies in both directions.
It's worth adding in the domain of constructing web servers, the list notation of Lisp maps extraordinarily well, and easily, to the hierarchical markup of HTML. It's a feature I've exploited extensively, and I think it could provide better and simpler tools for web programming if employed more widely.
