Why does Facebook Comments Box only support two levels of hierarchy?

My answer to Why does Facebook Comments Box only support two levels of hierarchy? on Quora

I’ve heard in the past that regular (i.e. non-geek) users often have enormous trouble understanding hierarchical comments—they don’t understand tree based file systems either.

There’s another problem with tree based comments, which is that it’s very hard to identify which comments have been most recently added.
