I considered doing something similar a while back, but just like snail mail, you cant avoid it if everyone else still insists on using it. I'm still dumbfounded that i have to verify my identity via fax for some organisation or by letter for government institutions. There's just no avoiding it. its the same with email. How will he deal with verifying his identity with a website that emails him the verification link? But more to the point, if it's spam he wants to avoid, or people trying to get his attention, he's not going to avoid that just by going to Twitter or Skype or anywhere else.
