I've been making more use of iWeb to maintain a "microsite" for my Constitutional Law class this spring. I provide summaries of the real Supreme Court's decisions in the cases we cover in our Mock Court exercise. I also started a podcast; there's only one "episode" up right now--an explanation of something called substantive due process.
iWeb is a quick, easy way to edit and upload web content, though it works most smoothly with a .Mac account. I figure that I'm paying for this service, so I might as well use it.
