It is fairly easy to configure Facebook notifications the way you want them to be (for example, I want to know when someone logs into my account, but nothing else). I post on my timeline less than once a month, and receive no notifications. Not to defend Facebook, but notifications are hardly its biggest annoyance.

My email preferences have everything disabled, double triple and quadruple checked to make sure, and I still occasionally get an email about one of my FB friends uploading a photo or some shit that is certainly (a) described by the settings as email I should not receive, and (b) not even what a notification should be. “A person with whom you’ve never interacted aside from accepting a friend request said something not about you on their own timeline.” ???

This is not true. They offer no fine-grained control besides dicking around with dozens of unsubscribe links over several weeks.

For instance, how do you easily configure Facebook to ONLY send you emails when you're invited to an event or someone sends you a Facebook message, but NOT when your friends post random stuff?

I have to agree on the no fine-grained control. My point was that it is easy to opt out of the notifications by email in general. I'm positive that there is an option where you receive a notification when someone send you a message, but I don't think it is possible to get event invitation notifications only.
