One of the major differences we've discussed in the past between Google+ and other social networks is the ability to format your posts. I've shared tips and techniques, and the renowned Peg Fitzpatrick recently ran through her style for creating the perfect Google+ post, and it's right in line with how I share new blog posts.
But why does it matter?
In 1989, Dr. Steven R. Covey published the landmark book, The Seven Habits of Highly Effective People. If you haven't read it, put it on your Summer reading list right now. In the book, Dr. Covey suggests seven daily activities that we should adopt in our lives to become more effective personally and professionally. One that I reference and paraphrase regularly is Sharpen the Saw (or Axe), which is a call to constantly be reading and learning in order to improve ourselves.
Once you create your profile on Google+ and begin to share updates and interact with other plussers, you will begin to attract followers. Other Google+ users will add you to one or more circles. If you're using Google+ for business, then it's important that you continue to attract more followers so that when you share content regarding your business, more people see it.
When Google enabled the creation and proliferation of Google+ Communities, they did indeed proliferate. In addition to general topic communities, countless other communities sprang up revolving around niche topics and questions, people and businesses, and anything else you might imagine. And since Google continues to make improvements to the communities and moderation tools, community use and growth remains strong.
