I just recieved this email from Facebook letting me know they will, going forward, be sending me less email:
This is awesome and I am really happy that they are starting to listen to users. It seems as though ever since Google+ has started their blogging and video updates, Facebook has started following suit and is doing it as well.
The only email notices I ever got were from people updating my wall or responding to a post I commented on (which actually was REALLY annoying and one of my biggest complaints).
Enjoy having less email!
