Works great, very friendly UI and isn't buggy.
Great developer tutorial; okay faq manager
That said, I ultimately couldn't use Example FAQ in production for a couple of reasons:
a) Each long-form answer is on its own page---a bit unwieldy in terms of both UX and DB-weight. This format is baked into to architecture and can't be changed.
b) Although you can modify and add questions, there's no way to delete them. (You can, as a kluge, assign them to a never-displayed section.)
c) The FAQ display format is tabular with element-level styling. I know this is acceptable practice per the C5 core; but for the end-user it's still a procedural headache to have to dig through php to customize design. Div-based structuring with a dedicated CSS file would be more flexible.
