On one level, the with the rest of the Google-verse is a benefit for the social network. But, on another level it is sort of creepy and difficult to manage.

Once you join Google+, it is instantaneously ubiquitous. Go to Gmail, and there it is--that '+Tony' at the upper left on the menu of links with the other Google services. Go to Documents, there it is again. Go to Photos, and...well, it's there, but now it says '+You' instead of '+Tony'. Go to Calendar, and...well, it's not there--but, you get the idea.

Click on your name at the upper right of any of the Google services to open the drop-down box for things like Account Settings, and you will notice a new entry on the menu--Circles. As you might expect, clicking it takes you to the Google+ Circles page where you can create and manage circles and drag and drop contacts into various circles. Interestingly, the drop-down box from Google Calendar does not have the Circles option. Apparently, Google+ is just not integrated with Calendar (yet).

One thing you can do with Circles is add users who aren't even on Google+. You can add Google account email addresses to a Google+ Circle, and when you post an update for that circle, the individual will get a notification email with a link to join Google+. However, it gets a little weird when you are on the Google+ page.

Google+ 'borrows' liberally from the in terms of the basic layout. On the right pane, Facebook will suggest other Facebook users you may know so you can connect with them. I am not sure of the algorithm used--whether it suggests based on who went to your same school, or who works at your same company, or some sort of association based on how many of your existing connections are already 'Friends' with the contact. I do know this, though; the people it suggests are Facebook users who already have Facebook accounts.
