You pose an interesting question, because you started by noting that it's a process of transition and it's difficult to determine what the appropriate defaults would be. Then you closed by asking if we should regulate that.
That's what forms my answer, which is that we're still in the process of evolution where we're trying to identify the appropriate format and the appropriate time and the appropriate content to help users make decisions about their data. We feel we made a tremendous step forward this year with our changes in our privacy policy, because we took what was a very long and complex document and broke it down to several very simple elements for users to really understand how we're asking for information and what we're using it for. That's an example of trying to take what is one big long notice and giving it multi-layered notices.
It's difficult to try to set regulations in terms of what should be included in those sorts of notices and that sort of discussion with the user without a period of experimentation. In fact, setting regulations often just sets the status quo in stone, and certainly in this space we're seeing innovation every week with regard to how we evolve our relationship with our users to make sure they are informed and have that sort of level of personal control.
