You no longer need someone's email address to send them an email. At least, that will soon be the case if you want to email another Google+ user. A new Gmail "feature" will let you simply type in anyone's name into Gmail's "to" field and send them an email. Google announced the new Google+ integration on its Gmail blog today, but company representatives have clarified to The Verge that - by default - anyone on its social network will be able to send messages to your Gmail inbox.
It's opt-out; so it's enabled by default. I don't think Google has ever had a more stupid idea than this. This is just all-around bad - no ifs, no buts, nothing. You must be completely brain-dead to think that implementing this "feature" is in any way, shape, or form, a good idea.
I'll be turning this off right away - I don't want random internet people emailing me any more than they already do. Equally idiotic, when you start typing a name in Gmail's to/cc fields, it will autocomplete to Google+ usernames. I have no idea if you can turn this brain fart off.
I don't like Google+, I don't want Google+ - I just want it to go away. Please.
