I also find that it tends to be more concise which lends to denser code. The density can be a bit off putting until you become accustom to reading it. The other part that is weird is having all of the closing parenthesis on a the last line. Consider the idiomatic way:

  (defn do_stuff
    [coll]
    (filter #(> % 10) (map Math/sqrt coll)))

Vs

  (defn do_stuff
    [coll]
    (filter #(> % 10) 
            (map Math/sqrt coll)
    )
  )

Even though this is the same code, if you are coming from a c-style background the latter is probably easier to read.
