Proofile is a personal data management service, allowing users to save basic information about themselves and share it across different social networks. Their promise is not a new one:
Are you fed up with entering your birth date, your interests and your
pet's names all over again, everytime when joining yet another web site? […] The data you enter into proofile is readily available to other web services, if you choose to export it.
Wide adoption of open standards is definitely a point in their favour, and it is undoubtedly a useful service, but I wonder whether its added value faces harsh competition from well established OpenID providers themselves, that might have the last word in managing a basic core of personal data – especially the information that is regarded as strictly connected with identity itself …such as the fundamental attributes that make a person identifiable not only by a machine.
