I especially like default use of groups and how it forces users to think about privacy from the get go. This is very different from my FB experience years ago and why I quit using FB.
Unlike Microsoft's control of the desktop, people choose to use Google everyday. It would be so very very easy to switch to Bing tomorrow (even easier than choosing not to use Facebook!) but people have chosen not to switch.
Just because you have a lot of marketshare doesn't mean you are a monopoly.
It's also quite easy to say that consumers will benefit from the increased competition with Facebook. This is what anti-trust tries to promote, not restrict.
It's very frustrating. I love the ideas in Google+ and want to use it, but I've got no ability to share or add friends.
It got even better once i realized that because of the way circles work, this kind of feeling might actually be preserved without much effort on my behalf.
I had to give up the site because I have to keep those lives separate for my own sanity.
Basically add everyone you want to circles and make a post. They'll likely get through the invite within a day or less based on my current experience.
The invite-only, throttled approach worked for GMail because you could use it to talk to people who aren't on GMail. Facebook's gradual launch worked because entire social networks (universities) could join at once. Wave and Google+, however, were/are worthless in closed beta.
It's because Google+'s social signal to noise ratio is so much higher than Facebook. I dread the red notifications in FB's upper left corner bc they're usually from some friend of friend's irrelevant spam event/survey/tagging etc. Google+ Circles really filters thats out.
Facebook's mistake was introducing Groups so late. With Circles, users can create Circles AS friends join. I will never retroactively organize my Facebook "friends" into Groups. I will, however, take a little time each day as new REAL friends come to Google+ to organize them to reflect real social structure.
Google 1. Facebook 0.
That said, it's not like there's a choice.
The fact that it's a different form of social network (more refined imho) and has new features (hangouts, circles) is bonus.
Google's bottom-line success with + will be the mitigation of the Facebook social search threat... anything else is gravy.

On the other hand, google+ has the might of one of the web's most powerful and innovative companies investing tons of R&D into the psychology and science of human friendships behind it. The fruits of all this research are plain to see in everything from the way it maintains circles to the implementation of hangouts. Ultimately, its just a better product. Not that it guarantees success, but it does a good chance at it.
Maybe Baby Boomers will like it over Facebook or not at all for either, if it's aimed at a younger crowd I can't see it working unless as stated it's forced upon people.
With iPads and other tablets and mobile devices becoming more powerful with bigger and better screens I think a stripped down mobile social network app would be the best way to attract attention or a completely different concept.
Facebook can easily mimic google circles. But, who will be better at combining search and social to add some new value to both?
And hangouts? It could be quite hard for someone to make a good implementation, and still have a huge user base as google.
Anyway, circles seems like the easiest feature to implement for the likes of facebook. Good social search, and group video chat, this might be more difficult (facebooks classic chat isn't even working most of the time).
If you're Google in 2011, you bake it into search.
All you do is make your core product heavier. The thing you wanted to kill doesn't go anywhere. It hardly notices what you did: http://scripting.com/stories/2011/06/28/googleYawn.html
Look at how Gmail contacts are treated in Google+, they're relegated to a stopgap. Look at the privacy settings for various fields in your profile - they default to sharing with your Gmail Contacts and once you chose a circle, you never have any context of Gmail Contacts anymore.
I love unification and data aggregation, especially with Google's Data Liberation efforts and the export they already have for taking your social data (potentially elsewhere).
As it is, I can't wait for it to die like Google Wave. More worthless web apps from Google will come to fill its place.
