One thing to consider, Google+ has a policy that you must use your real name. Unless or until they change or modify that policy, you need to consider that. Yes, you can still probably register under a fake name, but once they discover the fake name, you have four days to fix it, or get banned.
Update: I was banned under this policy.
Google+ is a young, growing, social network. Yes, kind of like Facebook. Yes, most of the world (they claim 750 million members) are on Facebook, but I'm not. Here's the link to a previous post called Why I Left Facebook Today.
What do you do on a social network? You act socially, either with small groups of friends or followers, or with the public at large. Some people use it for a status update - what they are doing at any particular moment in time, like "I'm drinking coffee and reading the morning news online."
Some people use it for a way of expressing a particular thought or feeling they might be having, like "I'm glad the library has extended it's hours on nights and weekends, and these are the recent books I've read from the library . . . "
Some use it to express longer thoughts and views on a subject, kind of like how I use this blog. With Google+ you can link to blogs, or re-share posts from other people, or put a video in the post, lots of different things. You can link to things outside of Google+ too. You make it what you want.
Update: No one is bothered by me, since I was banned.
Yes, there are some games to play too. Being an "Angry Birds" addict,
You choose who to follow, and who to share with by using the Circles feature. Just like in real life, you have different relationships with different people. They have some Circles set up for you to start. One for Family, one for Friends, and I think one for Acquaintances. As you find people on Google+, you drag them to one of those Circles, or make new Circles.
With Circles, you can choose to share your posts with just some of the world. I might post something that would only apply to other priests,
I can also export my data and leave Google+, and that's the feature I like the most.
One major thing to consider. Google+ is just starting and not a completely finished product.
Update: Nope, not the nickname, nor the title. C'est la vie.
