Others have touched on many of the ways that hashes are useful. I'll just add that, when I have a list of values, often I'll make them the keys of a hash right from the start, rather than putting them in an array, because there's a good chance I'll need them in a hash at some later point.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
