Facebook must really want users to use their messaging system. The social network has changed users’ default email on their profiles to one that ends in @facebook.com.
"As we announced back in April, we’ve been updating addresses on Facebook to make them consistent across our site," Facebook said in a statement to CNBC. "In addition to everyone receiving an address, we’re also rolling out a new setting that gives people the choice to decide which addresses they want to show on their timelines."
Facebookusers’ new Facebook email address can be used at the same as traditional email, and anyone sending to a user’s Facebook email will show up in Facebook messages.
