I'm curious how they verify someone's real name?
How does this work for people who use a name that isn't their legal name - this could cover everything from people preferring another name (not uncommon), to transgendered people. Although if you can just enter fake info, it's less of a worry (Facebook seems to be like that these days - although I believe that it is or was against their TOS, and they have banned people for not using their real name, so there's always that risk).
The new generation doesn't give a damn about privacy and actually longs for everything you are afraid of. They sign up on facebook and other social networks writing everything (true, not fake as we used to do) about themselves, they take pics of them half naked and share them with people that are unknown even "digitally", they "make friends" with unknown people.
Whilst I share concerns on people's attitude towards privacy, I don't think these criticisms are fair.
* Facebook has security controls on what people can see, and not everyone on there posts absolute everything. Facebook also receives plenty of criticism when it has privacy problems. I also dispute "true, not fake as we used to do" - indeed, in the earlier days of the Internet, using real names and talking about everything on Usenet etc (which has no security controls, unlike Facebook) seemed to be far more common than now.
* I'm not sure why getting to know someone online means that they can't know the person. Even if you think that, there's no reason why others have to. I don't think that sharing a half naked picture with someone you've got to know online implies a lack of privacy. How is it different to picking someone up in a bar and having sex (putting yourself at far greater risk than online)? Or indeed, people who strip or pose nude in public?
* If by "make friends" you mean friending someone, then this is just a misleading term for technical aspects. I don't see how linking to someone means I'm giving up my privacy - just because the website calls it "friending" doesn't mean anyone thinks of it meaning that.
Old generations aren't better - the tired old "Nothing to hide" etc.
This kind of thing always sounds like mass hysteria to me.
I don't have any problems in having the public details of my life shown. If they are private I simply don't post them/ give them/ upload them, no matter what... the same thing I do I real the world!
Do you walk around with a name tag in the real world? Can everything you say be preserved and easily searchable forever?
Just because I post something on the Internet, doesn't mean I want to give away my full name to everyone. And judging by how few people use their real name here, I imagine lots of people share that viewpoint. Yes, in the grand scheme of things, I'd worry less about this site than some other sites requiring this. But there are some worries, such as stalking, or potential employers googling you and having something against gamers. Plus, aside from the public issue, it ought to be none of Blizzard's business, either.
And what's the reason in favour - that it would stop trolling? Hardly. If you want to make comparisons to Facebook, then you should know that trolling and asshattery exists just as much on Facebook, despite people usually using their real name.
The funny thing is, I would bet, that most people who are against these measures also have public profiles with lots of personal information... like facebook, linkdn, picasa, etc...
And I bet you're making a straw man.
