What blew me away was when I signed up for UPS alerts. All I provided them was my birthday and street address and they managed to connect everybody I knew -- despite my having a very common name. It even knew who my sister was, her married name, her birthday, and street address. I only use Google+ at work. Apparently, it wasn't able to connect my work email address (I used a fake birthday, too) with anything. So, I'm relieved about that, at least. > From: bh > Date: Sun, 14 Apr 2013 18:11: -0700 > > So, I finally started working on the Snap! tutorial videos, and > yesterday I uploaded the first one to YouTube, which involved > making a YouTube account, which apparently you can't do without > also making a Google+ account.
