Well, short pages can be viewed either in Special:ShortPages or via the API's list=allpages. But short pages are probably divided into several categories: I like the idea of __NOSTUB__, but adding it to pages is pretty much the same idea of adding STUB to short pages, only the other way round, i guess :p So you should probably rely on the links above and then use your judgement to see what page needs to be marked as a stub.
 * Short incomplete stubs
 * Disambiguation pages or lists- normally very small in size
 * Redirects- shouldn't take more than a few bytes
 * (as you mentioned) articles about a topic that has very little available info out there, so all the relevant info is already in the page and yet the result is a small page size. Therefore, making it longer would simply make readers waste extra time for reading the exact same thing- something everyone should avoid.
