The user interface is clever and (mostly) intuitive. I love the ease with which I can choose who to share each posting with. I also appreciate that I can share my postings with friends just by entering their email addresses. They don’t have to be Google+ members to get copies of my postings. (Of course, they can unsubscribe from the email notifications so I won’t be spamming them.)
Check out my posts on Google+ and join the fun over there.
