I too am on the rampage to kill email. I had such a stressful last few years in corporate — largely down to email and that other curse meetings — that I would love to see it go in favour of social tools and plenty of them are there to use.
So from 1 January I am going to do a similar exercise. I will coach people who email me OFF of email.
We are up against corporate systems that don’t like Cloud or SaaS products but I am going to do this.
One exchange at a time.
I’m going to start by switching off alerts from OTHER tools into email (like LinkedIn and so on).
See you on Google+ etc.
