Yahoo email is unusable with all this ad spam. There is zero reason for not changing to Gmail.
I have already started to change all of my accounts to use my Gmail. It is impossible to get anything done in my Yahoo email with all of the spam about password protection and premium subscriptions when it offers literally nothing more than other FREE services that don't spam you. Until Yahoo offers literally ANYTHING more than the obviously superior choices out there I will not be using any Yahoo services from now on.
