Of course, I feel a similar way about Facebook. I know a lot of people use Facebook avidly, but I almost never do. Every time I log onto that site I regret it. At least on G+ I can aggressively tune out the boneheads with some hope of success and without incurring a ton of social kickback.
And here you overplay your hand. You have no idea what Twitter's main userbase is.
I haven't seen any real value demonstrated from it, except as a marketing gimmick my Google. The number of reported "+1's" means absolutely nothing to me.
It's inevitable. Get over it. Or rather, get empowered by it.
Google's play here is that they have this data for when you click through–and it's been helping them for years–but now they're exposing it to you. So you get the benefits of big data analysis in a context you can understand. Instead of being some sort of back-alley data collection initiative, +1 makes the whole process very much an up-front-and-transparent thing, complete with data export. \
I'm not sure how much more consumer-friendly and empowering a feature can be. Society wants the benefits of big data analysis and so companies have to find ways to make it valuable, transparent, and straightforward. How is this relationship any different from your relationship with Mint.com or Simple?
Allow me to give you concrete cases. I was looking for a good raspberry pi breakout board so I can use the GPIO without concern that a bad soldering job would lead to a dead board. I type this in and I see those little people and +1 notifications for some products and blog posts and not others. I also see promoted images from a friend who just installed one.
I have a fairly good idea about the authenticity and trustworthiness of these people, and so the search results have helpfully incorporated this data and helped shape my purchasing process.
Now, I have made it a point to cultivate relationships with people in this space that are also G+ users, so it isn't "free", but it pays off pretty handsomely in cases like this.
Is that not a clear enough value proposition?
In all seriousness, I think Google+ is a massive force. If you play the SEO game at all (and let's face it, most web companies do at least a little bit), then you have to pay attention to Google+ because it's showing up on search results. That makes those web companies more invested in getting their users to use Google+ and encourages adoption. Circular, strategic, very interesting to watch.
But on country by country basis, Google+ gets the most users from US by far:

Every last one of these people is based in the USA.
Google+ might be popular in a geographic part of the world, or among a certain community I'm not part of, just like Baidu is in China, Rakuten is in Japan, Vkontakte is in Russia, Orkut in brazil, etc.
I just have no idea, and it seems I'm not the only one, what this demographic they have conquered is.
