LinkedIn CEO Jeff Weiner has been quoted in the Business Insider, stating that users won't find time for Google+.
It would stop at that, I would call him a fool. But then, later in the article, he mentions that, for Google+ to work, another social platform will have to fall.  Let me tell you who will fall and what to get from it.

Let's start with the cool stuff: video, chat, mobile, and yeah... the circles.

The circles are one of the smartest dumb idea I have seen so far: A graphic version of Facebook lists. Nothing innovative, it's just easy to use.
You hear, Facebook? E.a.s.y.

Video and chats come next, while FB chat is heavy and erratic, Google serves us with their excellent implementation of the XMPP protocol we all know via gTalk. On the interface level, the chat is not intrusive and actually lets you CHOSE when you want to discuss. And it does it with video.

Where it surprises: 'sparks' and 'incoming', or the end of friending.

Sparks are a good way to get the information you need based on your interest, while 'incoming' will show you the streams of people who're following you but you're not yet following.
These features are already powerful when looked at individually, supported by the Google's long experience in feed reading and struggles with privacy and/or data relevance. When combined, they simply mean the end of Friending. Which is not a bad thing.

Where it bites: integration.

Google has everything: Search engine, e-mail, chat, apps, browser, calendar, maps and places, news reader, document viewers and more...
Now, that would be really stupid not to take advantage of all this pre-existing material, right?
What you can be sure of, is that Google+ intends to become a full fledged OS and Web integrated platform, stretching from enterprise integration to social gaming.
Just take a minute to look at their already killer notification system, accessible from their search engine or from gMail, you'll see what I mean.

Where it hurts: mobile

One circle to bring them all and into the darkness bind them.
One little mobile application, a framework to link G+ to android apps and there you go, you've got yourself an all in one solution.

Facebook and Twitter: punched in the face.

You don't need friending on Twitter, but the looking for relevant data is a brain torture. You like your good old Facebook, but not only it's getting more crowded with adds everyday, it also gets more complicated and, come on, it's so 2007.
The truth is, Google+ has the potential to do everything Twitter and Facebook do, but better, with a cleaner interface and all the additions listed above.

The coutdown: RIP, RIM.

Research In Motions has been launching betas of his social framework for BBM for a while now, and we're not seeing anything consitant yet.
This is too bad for them, since they don't have anything to offer save their 'exclusive' enterprise and messaging services.
Their primary mistake was trying to do it alone, sticking to their own closed systems and proprietary hardware. While they were trying to reinvent the wheel with the Playbook and their new not-so-innovative-anymore social feats, they jumped-in way too late, with too little to offer. Google just went around their strategy and did the exact opposite, offering a comprehensive app suite available for everyone.

I don't see them getting out of that situation unless they do something drastic, such as opening BBM or porting it to other platforms.

Collective Asses given a life lesson:

Trial and error. That's about it. We've been repeatedly laughing while pointing at Orkut, Wave and Buzz while big G was jubilating, watching the critics pile up in the shape of a nice how-to for there future product.
My skeptical self still believes (as, apparently, they do) in the 'wait and see' approach, but G+ is adding a million users a day and has a surprising level of maturity for a product so new. I see a huge success, cake for everyone.
