The "Friend Request"
While it's easy to say it's "Facebook but not Facebook" I'm starting to realize that's fundamentally incorrect. I mean, yeah, you could use it exactly like Facebook. But that's not its underlying rationale and structure.
Really, it's basic structure is more Twitter-ish. By default you might fire off Public Posts that anyone who is following you can see. But you have some subsets that you share more personal stuff with, like Family or Friends-only, and Google+ is happy to oblige you.
This is different from the Facebook model. Note that to see what others do, you just need to follow them. It's a unidirectional transaction. Contrast this to Facebook where you have to confirm your Friend Request, and then everything is shared between the two parties bilaterally. In fact, I have several people on Facebook I've friended then summarily hid from my feed 'cause I'm using it like a Rolodex and don't actually care about what is going on in their lives, or I don't share things with my "Limited" friends because I figure I'm not as caught up with them, they probably don't care about my stuff anyways.
Obviously you can replicate this Facebook Friend behavior. Google+ tells you who is following (but not what circle you've been placed into) and you can promptly follow back. Friend Request Accepted! Commence 2-way spam! (This is also apparently what most of use are doing right now)
However, really what following someone means is not "are you my friend" but instead "do I care about what you post and share and see what is going on in your life." And perhaps it's mutual. Perhaps it's not.
The Subsets and Supersets of Circles
Google+'s main cool feature is a really, really nice way of organizing your friends. These Circles though allow you to share stuff with specific sets of friends. Some of the obvious ones are Family-Only announcements. Some more creative ones I'm are people making specific lists for sharing a particular part of their life, like music they found or links on the internet. Personally I'm building a "Spammable" circle for my link propagation habits. (These are often opt-in and people will post seeing who wants in. Hopefully a feature will come that will allow us to make these circle opt-in from the other side instead of us manually sorting the masses.)
Since we can place the same person in several circles, you suddenly have a very interesting potential set of overlapping circles, just like modeling your real life. Currently I've sorted people mostly by my relationship to them, and the Spammable circle is a way to mash a bunch of them together from disparate parts of my social network. This way I still have a network of individuals sorted, but only the closer ones regardless of other circles get my spam.
Of course, if you instead want to use it as originally intended, just push most of your stuff as Public and use Circles for specifically targeted messages and conversations. I'm sure as time goes on we'll see more ideas and structures develop using this feature.
HANGOUT ARE AWESOME
Probably the most badass feature so far are Hangouts. It's group video chat, up to 10 people. Sure Skype and Ventrilo and many others have similar things, but Google+ has 2 major advantages.
Sure, there's video. And that's kinda awesome to see people's faces again and their expressions as they laugh or give you the stare.
The kicker is the natural casual nature of the hangouts. Two people can just be "Hanging out" and a button shows up on Google+ to let you join in. Boom, instantly you're in! THAT'S AWESOME!!! It's like my olde East Dorm Lounge. Walk in, people are there, chill, leave when you want. None of this "setup a call" or "did so-and-so invite me to that group". Well. You could do that via Circles and just not invite people. But still, Hangouts provide a really nice way for people to just walk into the meeting and chill with friends. This feature alone is egging me on to finally buy a webcam. (I know, no smartphone, no webcam, still stuck in the 2000s)
Google Integration
A really, really sweet feature is you can see the notifications on any (well, almost any) Google App page. Your top bar that typically tells you all the Google Apps you can switch to gains a notification spot and a field you can use to quickly share something you just found.
Number shows up for how many notifications you have, you can review them and quickly see just the updates, then resume your Gmail or Google Searching. That feature alone, that I don't have to keep a Facebook Tab open, is gonna be the downfall of mankind's productivity I guarantee you. And instantly sharing? Oh goodness me.
Still some Rough Edges
So, that Google Integration? Somehow it doesn't work on Calendar. D'oh. Also, using the "Share" system on Google Reader doesn't appear to load it into Google+ (yet). And Vimeo video embeds don't work. And they won't let us invite more people. And apparently it hasn't rolled out to Google Apps so go setup a GMail / Google Account if you want to partake. And obviously since it has no data it can't suggest people to you very well yet so you'll have to search people manually.
EDIT: Apparently it doesn't catch my Blogger Posts either! /EDIT
"Better" Privacy
Well, at least it's not randomly popping stuff up like a stalker on other pages and it's way easier to only send stuff privately to a subset of your buddies and there aren't any subversive data mining 3rd-party applications, but you know Google wants all your data. COOOOKIES. OMNOMNOMNOMNOMNOMNOM
But seriously, even with the Buzz and a slight oopsie here, Google has had a better track record on privacy than Facebook. And while it's still getting out the kinks in letting me custom tailor my privacy settings to lockdown mode, the bonus of using Circles to carefully cull who gets what sensitive info is a huge plus already.
The BIG Question:
Will it beat Facebook?
Dunno. The biggest issue is can you get the adoption rate? Social networks like this only work if everyone else is using it so you use it too. And getting that critical mass is what makes or breaks it. Also, tearing people away from Farmville.
For most of my friends, we're flocking to it ASAP. So, it's gained critical mass for a few of my circles. But there are several other still left out in the cold. Even with some of its oddities and bugs I like it and frankly I bet a bunch of my non-as-tech-savvy friends would like it too.
