I'm always conflicted about long-form writing. Particularly when dealing with senior management and executives, the "wall of text" is a great way to ensure no one actually reads what you have to say (edit: unless, like the OP, you work at Amazon where Bezos established the notion of the 6-pager).<p>In those circumstances I tend to opt for inverted pyramid writing, in the hopes that the skimmers will get the gist and folks who really care for the details will get what they need.<p>But it's a tough balance, which is why it's critical to a) know your audience and b) have a clear understanding of what you're expecting when you're communicating. Are you sharing information? Communicating a decision? Seeking feedback or approval? All of those may require flexing into a different style to be most effective, particularly when taking audience into account.
