Not really. The main thing that has been happening over time is that more and more low-security messages are being drawn away from email (Twitter, FaceBook, SMS). I used to get email forwards from friends/family -- now they post to FB. I never get a pic emailed to me any more. So, the trend to separate out low-security messages has been happening -- perhaps trending towards leaving email as only a password recovery mechanism.

Or maybe not even that -- I use 2-factor for Google and FB -- where SMS is in the mix -- SMS could even be the recovery mechanism, moving even those messages out.
