> How are people getting their email address wrong so often? Invalid generalization from the process of signing up for email itself. When I sign up for Gmail, I choose an identifier I don't control (and computer says no if I get it wrong). Then this becomes my identifier. Likewise for usernames. So if emails are now usernames, why would the same process not apply? I choose an identifier I don't control. I put "@gmail.com" because it says to use an email address and that's what email addresses end with. Computer doesn't say no so I must have done the right thing. Rinse and repeat.
