The technology is re-defining the ways we live. I think that we need to define a set of new rules how we're using technology. For instance, the ideas may be:
* not publishing someone's data if we are not sure if it is true,
* a way to rapidly remove information about us/others that is harmful,
* protect children from posting the information they shouldn't (addresses etc)
* add a right to "forget" some information

And we need to balance all that with the freedom to speech. But we have no other choice than to find the new way :)
