+The default weight for any piece of content is 0. Zero means "does not have a weight", not "has a weight of numerical value zero".
 
-Weights of zero are treated specially: if two pages have unequal weights, and one of them is zero, then the zero-weighted page will always appear after the other one, regardless of the other's weight. Zero weights should thus be used with care: for example, if both positive and negative weights are used to extend a sequence in both directions, a zero-weighted page will appear not in the middle of the list, but at the end.
