Google+ (Google Plus) is a brand new social network that I'm sure you've already heard of by now. Looks like the big G is ready to take on Facebook now, but it's too early to say how it will shape up.
The overall "look and feel" of Google+ is quite similar to Facebook, but it has unique features like Google Hangouts, Google Sparks, Google Huddle, Instant Upload and of course, Google Circles.
Google+ is still in its basic state at the moment because it's being back-tested with limited number of users. I've used Google+ for a few days now and one of the main features that I like is Google Circles which allows you to create your own cliques of friends. Circles are unique because they allow you to maintain privacy of your status updates, newsfeeds, etc. with only those cliques.
The other neat and unique Google+ feature is Google Hangouts which allows you to video chat with up to 10 of your friends from different Circles. I've created a Squidoo web page which provides a more detailed coverage of the key Google+ features with video overviews of each.
At the moment the social networking platform is not open to the public and is by invite-only. If you know a friend who is on Google+, you can request an invite. Though, I believe Google is still monitoring the influx of invites and rationing them out.
If you'd like a Google+ invite feel free to Contact Me and request an invite. Beware not to leave your email addresses on public forums and comment sections because unscrupulous people could harvest your email address and spam or scam you.
