I WHOLE-HEARTILY agree with you about development presets. In fact, I've almost forgotten to teach them! I explain to students that I almost never use them because I always look at an image and simply ask what it needs. I've been working with Lightroom since 2006 and just STARTING to be open to the ideal of presets, sometimes, but find them limited. For example, I thought I'd create graduated filter presets, one each for the top, bottom, left, and right, so if I needed more than one, just click the preset, right? Doesn't work that way. They aren't cumulative, so when I would add the 2nd, the 1st would disappear. Thanks Adobe! I think it's almost criminal the cottage industry that traffics in presets. Not that I have an opinion...
I don't teach Publishing Services extensively, as I and most of my students are over 30, and generally not interested. I rail against FB because of the abusive copyright stealing. And in Lightroom, you can't manage your FB site, so it's not like you can remove images from your FB collection, and have it removed from the site. Also Lightroom posts that the photo was posted by Lightroom. I also don't teach about managing derivs. I tell students that after they export and do something with their images, then trash them. I figure I'll be better at Lightroom next week then this week, so I might as well re-visit my settings.
I definitely teach printing, and the concept of getting your images out of the computer and showing them to the world. I started teaching a class at Stanford last night, and am requiring them the engage in a photo project by the end of the class to get their images OUT!
