Zohair Hyder writing on the Official Gmail Blog hasannounced “A better Google+ notification experience in email”.
Google+ notification on the phone; replying via email; updated post in the stream
“On the desktop, in addition to adding people to circles, and viewing recent Google+ content in the people widget, we’re now making Google+ notification emails in Gmail completely interactive:
You can view, comment on, and +1 posts from inside your inbox
Your comments appear in the Google+ stream in real-time, and
Responses from others instantly appear in Gmail, as part of the notification message.
You can also reply to notifications from your mobile device (and/or POP or IMAP client). Just open the notification email about the post you’re interested in, and look for the new prompt, “Reply to this email.” Tap reply, send your comment, and we’ll automatically add it to the ongoing Google+ conversation”
