Lisp Questions

So I have some questions about lisp. I've been learning programming but I hear some conflicting information so I need some things cleared up.

First of all, I keep hearing that the ability to wrote code others can read is huge, but since lisp is incredibly hard to read, wouldn't that make lisp programmers inherently bad programmers?

Also, can someone post some non-trivial lisp code? Every time I see someone post lisp code it's always something very short and trivial. Is it possible to write anything real with lisp?

Here's a tip: use Chicken Scheme

Although Racket might be more friendly to experienced programmers, Chicken follows the SICP terms more closely I think. Chicken even can be aligned with MingW and compile to standalones pretty easily, and there's tons of libraries as "eggs", besides supporting scm files and tons of others.
