As I said above, if your code is loaded down with tons of long lines of code, it's likely a symptom that something else is wrong. If code is difficult to read, it's bad code.

Isn't perceived difficulty of reading code correlated with how familiar one is with the language it's written in? For example, code may be harder to read for someone who lacks experience or is new to the language, but it's not difficult for someone who is experienced and is familiar with the language.
