I've seen payroll, scheduling and appointments and a Blackboard-esque system built on top of Wordpress. Barrier to entry is low and there's a glut of cheap Wordpress developers out there, too, so companies that don't have a budget for an entire IT department can still get by with hiring a few engineers when they're needed. Again, not my first choice, but it seems to work.
