Most of Sylvar's writeup is good advice.

  1. The title of this node should probably be choose short titles -- you shouldn't capitalise without good cause.
  2. Metanodes should generally include that word in the title. A textbook of psychology would not be called Psychology Textbook, because it is about psychology not textbooks. But an index of psychological literature probably would be called Psychology Index, because it is not about psychology!

But still, when you pick titles carefully, you should choose short titles.
