I am glad to see that not everyone is obsessed with anonymity. There is so much more to Bitcoin, just like there is so much more to education and grades than keeping your grades secret from others.
The original poster is
obsessed with anonymity
He just thinks this would be a great tool for people to check their anonymity. Just like port scanners and exploit frameworks are great tools to check the security of web servers.
I also like the comment of Phinnaeus about the "look-at-me society". People do not always choose for anonymity: sometimes publicity is more attractive. However, I believe this should always be a choice.
And I don't think this datamining-idea is the right thing for showing that a certain transaction belongs to you. It is much easier to do that reliably with a sort of signed message system, maybe with a sort of Public Key Infrastructure for identity verification.
This, to address the bolded phrase above:
Bitcoin has properties only barely explored yet. We don't have to be limited to commonly known forms. We can invent new forms. Some will ensure privacy and anonymity, some will provide positive identity. We can wear payment codes publicly and we can conceal private keys in many ways. Without the Authoritarian Architecture of a Central Bank, we are free as individuals to invent new ways to create transactions and will inspire the Open Source developers to create new tools for us to make our lives easier and more convenient. And we will never have to worry again about someone stealing our money through the many frauds of identity theft.
