Make sure that bulleted lists have similar items, grammatically. Bulleted lists are a compact and memorable way to convey information, but they become less readable if the items don't match, grammatically. Typically, the list is introduced by a sentence fragment, and each item in the list is an optional ending for it. So, for instance, if the list starts out as a list of nouns with modifiers, it shouldn't have any items that are verb phrases. Be rigorous in using categorizations.
Categorization is a powerful tool for breaking down complex information.
Unfortunately, sloppy construction of category sets often makes them confusing. Categories are too broadly defined, omitting important limitations. Password compromises are a good example. This category does not include inappropriate disclosures of system content by personnel who are authorized access to the data they divulge. Classifications equate items that are not of equal value, or that don't belong on the same level.
