I just have my Google+ profile account after got the invitation from Problogger and LiewCF. Currently Google+ is not open to public and new registration can only be made via invitation only. If you don’t have Google+ account, you can drop a comment below with your Gmail address and I will invite you to join into my circles.
However, Google+ does not provide friendly or short profile URL like Facebook. Instead it uses long URL with your unique Google+ ID which is really difficult to remember or share with your friends.
