Even if you're not offering up information for commercial reasons, you need to come up with a goal statement. Once you have a goal, keep it in mind as you create every single page. In fact, each page should have its own goal. I can't say this enough times. I've visited too many sites in which you wander around five or 10 pages to find that at the very bottom there isn't anything to see.
Content is king.
If you've got content, show it. If you don't have anything to say, don't let those HTML files off your hard disk. If you have just enough content for one page, then keep it at that. Of course, there could be divergent views on whether what you have to say is useful or not. If it isn't, you could end up on the Useless Pages, which is not where I want to be when I grow up.
