<script type="text/javascript" src="https://apis.google.com/js/plusone.js"></script> this is standart code for g+
you have to create an account in Google +. then start sharing your site or idea there. just like we do in face book. you can also use the Google + button in your site. if people want to follow your site they can do it by clicking in the + button
Google+ is social network, the early adopters always seem to want to talk about the actual network itself. You can use google+ button at your website like as facebook like button.
Google Plus is social media like Facebook. If you know how Facebook works and what are the functionalities of FB than you can easily understand Google Plus.
