First, there needs to be lots of [STRUCTURE] that makes it easy for people to skim through and pick out the specific information that they want to find out about [...]

Grr!  I have no idea why that word got dropped out, since it was kinda important... writing too many words at once puts my brain in a fog.  :-)

Also, just to clarify I don't necessarily mean structure as in explicit headlines so much as any kind of structure --- including implicit structure from paragraph breaks and careful choice of presentation and ordering --- that makes it easy to pick up on how a text is broken into logical parts, what each part is roughly about, and how the parts are related.

Cheers,
