What you overheard in the park today is hardly evidence of some kind of trend. Google+ isn't even open to signups yet and is on an invite-only basis, used mostly by celebrity bloggers and other tech personalities who think every new social networking site is the greatest thing ever. Even the name "Google+" and the use of "+1" is too techie and mathematical for a lot of people.
