The future internet, no dogs allowed

Online identity: is authenticity or anonymity more important?
Before Facebook and Google became the megaliths of the web, the most famous online adage was, "on the internet, no one knows you're a dog". It seems the days when people were allowed to be dogs is coming to a close

The argument (and trend) seems to be that real identities enable more people to trust the web, and thus take part in it :
"Allan believes the benefits of authentic identity outweigh the costs. Facebook and other services with an assurance of security and credibility are more inclusive, and open up the web to new audiences who never would have gone online before, he says. "We're optimists. Facebook enables hundreds of millions of people to express themselves online because they didn't have or know how to use the tools they needed." Facebook, he believes, is a stepping stone to the rest of the web."

My personal position is that while it would be good to have consistent identities online (regular use of same psuedonym, or a limited set of psuedonyms, across platforms) there are many reasons why this should not mean real life identity. The biggest reason is perhaps the dangers people would expose themselves to, from the obvious cases of antagonizing a repressive (or even democratic) systems laws to the more widespread risk of 'peer-to-peer' persecution and mob justice. The internet often brings out the worst in both people and state in how they react to perceived violations of norms and values, and revealing one's true identity would expose one to this. Of course it may be argued that if everyone is identifiable then the risk from trolls etc. is also removed, but while this might temper it, and prevent outright illegal persection, it would not prevent plenty of malign and vindictive behaviour. Furthermore it is a fact that the nastiest people are often the most passionate, and hence most likely to go to the effort to bypass any authentication system (something which will always be possible no matter how well implemented).

Furthermore, on a lower level, but still important, there is the problem of interaction with real world relationships - friends, acquaintances, co-workers employers etc. The sharing and linking of the web means anything one says or does can easily be passed on, taking it out of the intended social circle, and out of context. The result would be that, if real identities were necessitated on services such as blogger, one would have the option of either limiting who can hear to a (hopefully) trustworthy small circle of friends, or resort to comments so bland and innane as to be worthless (and even this might not work, since even a fair and balanced statement might anger a racist or bigotted associate).

It is interesting that such a anonymous-but-traceable approach is supported even in the restrictive regimes of China and South Korea:
"An online identity can be as permanent as an offline one: pseudonymous users often identify themselves in different social networks using the same account name. But because their handles aren't based on real names, they can deliberately delineate their identity accordingly, and reassert anonymity if they wish. Psychologists argue that this is valuable for the development of a sense of who one is, who one can be, and how one fits into different contexts. This kind of activity is allowed even in countries where social network account holders are required to register for a service using a national ID, as in South Korea and China; their online public identities are still fabrications. Even with this explicit link with the state, when users are aware that their activities online are traceable, identity play continues."

This would make it seem that in some ways China is more permissive than Google, since although the state might want to know if you're a dog, it will still let you bark around the virtual park if you want; when it comes to Google+ however, no dogs allowed.
