What the Heck is Going On with Facebook email?

I just tried sending an email on the Facebook site and I got a message in red saying that it could not be sent. Thinking it must have been some kind of fluke, I exited the page and returned to my Inbox to try again.

This time the email went through, but displayed the following message:

Soon? How soon is soon?!

This, people, is exactly why social networks are not a good replacement for actual email systems.
