I don't know much about Google+, but a while ago, I seen on a website a warning that if you add you phone, it uploads all of your photos to there. Then directly next to that warning was an ad for Google+. X)
I think its more of a point to get away from close friends and meet more people. You don't send friends request and such, you just add people to a circle and you're able to see their posts unless they post to their own circle and not to public.
And they recently added communities which enforces that whole "Meet new people" thing
Makes sense. :x
I just don't add people in the first place haha. I seriously have like 20something friends. X) Some of which never actually post. I only ever really talk to my best friend's brother, my cousin, and occasionally my aunt or sister.
A lot of them I just go to school with, but with them on there I get a wide variety of events that I wouldn't see otherwise. Like free tickets to the Gay Marriage Debate because the leader of the LGBT club is on my facebook even though I've never met him, haha.
So after reading back Facebook/online friends is the topic right now, right?
Anyways, I don't have a Facebook anymore, had one a few years back, got disabled for no reason, probably for the best all my friends posted walls of spam xD
