Sure, but before I do, the question at that time was "How do I know if I'm a hoarder or not?" You are not a hoarder if:
You adhere to limits (financial or otherwise)
You know where every item is
If you are standing on the same property as your collection, you can physically touch any collection item in two minutes or less
Your collection items are not exposed to the elements
To Bill's credit, he met most, if not all, of these conditions.
Some musings:
