One of the purposes of writing, at least for me, is to get my message across to as many people as possible, who might benefit from reading my articles. I'm writing about health issues, and the many half-truths and outright false information that is out there in the media. As such, I can't say I'm oblivious to boosts.

As far as constructing your post is concerned, I think you have nailed it. Particularly what you say about the introduction. It must jump out and grab the reader by the neck. If you manage to do that, half the battle for their attention span is won.
