I think you are missing "problems" in this part of the text (see bold "problems" below):
Select an informative title. "Need help ASAP" doesn't cut it. Neither does the name of any Perl function.
For example, if you're having problems dereferencing an array in a hash, SOPW won't accept a one word title like "%hashref"; %hashref problems" isn't fully descriptive; but "Why doesn't this deref the @arrays in my %hasref?" is probably OK.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
