I have a blog dedicated to end users. It's called Consultant or Amateur. It's designed to be a place that gives advice to end-users AND as a place you can point your clients and say, "See. This guy's telling you the same thing I'm telling you."
I just posted a click-by-click article on how to download and extract your data from Facebook. The idea is to help folks take this seriously - and clean up the stuff they don't want associated with their profile.
If you are not currently helping your clients manage their social media presence, you might consider that service. If nothing else, this breach should give you a new slide to put in your standard security presentation.
Use it as you see fit.
