While looking at EllisLab's ExpressionEngine as a possible solution for an upcoming project, I came across this little gem: EllisLab's MojoMotor, billed as "the publishing engine that does less". There are no advanced content management features, but it provides a very easy, very slick on-site page editing/management experience ideal for non-technical people who just need a very basic web presence, such as busy small business owners, club organizers, and your mom.
I haven't tried actually installing it anywhere, so I have no idea what this thing looks like under the hood, but I liked what I saw in 15 minutes messing around with the demo (which, oddly, is not linked from their main site; I had to Google it). It is a commercial product, but at $50/license, it's priced pretty affordably. If you're a freelancer looking for a simple, easy to use solution for your clients, it's definitely worth a look.
