It's the first email service to come from the app, and while it hopes to reengage users who have looked the other way, TechCrunch speculates that not everyone may wish to receive extra email in the age of spam.

They say the new feature could, however, help users filter their content, weeding out the compulsive posters and seeing more of their real friends' posts.

Meanwhile, Google is soon going to launch a new online photo-sharing service and storage option to compete with Instagram. Google offers a photo sharing service known as "Google+ Photos," which comes pre-installed with every Android device. Google+ Photos automatically backs up photos in the device to Google cloud storage.

The new photo service will not be a part of Google+ network. It seems like the company’s attempts to bolster its product lineup and compete with the increasingly popular rivals like Facebook or Twitter to grow its user base.
