It's my theory that Facebook actually does this on purpose; notifications are the catnip that keeps drawing us back, click and clicking, making them money on ad impressions.
Ultimately though, they should support the change I'm proposing. People would interact wth more posts, pictures and links on the site if they didn't need to fear becoming mired in notifications.
