Before, 99 % of internet surfers were anonymous. Now, when they browse their facebook intranet, everything they do is logged and recorded. And now, we see the same with Google.
I tried to register a youtube account for my foosball association a few days back. It wouldn't let me use a nickname. It had to be a real name with a gender, a google+ account and a gmail. I ended up using my own youtube account. They've asked me about 15 times if I want to use my real name on youtube, I always say no.
