I noticed on some news sites I peruse, they put a point list summary at the beginning, complete with the answer to whatever problem the headline describes. Of course it is shallow enough that you still want to read the article to get context and a fuller picture.

This article might be describing some of the reason for the change in content format on the sites I've noticed. I quite like it in general, since it saves reading 3 pages to find out the answer is something you already knew from an article 3 weeks earlier.

Secondly, I think the tips are good for writers in general, even if you're writing an internal-only document. I'm a technical writer and reader, and my tolerance for tech fluff is unsurprisingly very low. I greatly appreciate leaving out the "some people" vague salesman style pseudo-observations, as they rarely come across as real in the first place, and instantly make any actual claims seem just that much more puffed up.
