That is completely subjective, and your example is bad. What's more readable here...
> (+ 1 2 3 4 5)
or
> 1 + 2 + 3 + 4 + 5
In my (subjective) opinion, the first one is. The extra +'s are redundant and noisy, and sacrifice a meaningful syntax for "trying to read as plain english". The syntax of any language takes practice and lots of reading - that's not unique to Lisp.
