Thank you for that question.
You're right: there's a constant evolution. When we look at the marketplace right now, not just at our product but at any company's products, you can see this in your daily experience. The screens and the notices that you're given when you sign up to use new products, to download apps, and to use new hand-held devices are constantly changing, because they're reacting to consumer needs. They're reacting to the input of privacy and technological advisers.
We're arriving at a place where we're starting to see notices that are more complex—sorry, not more complex, but that give you more information about the decisions you're making at that moment and that give you the opportunity to make an immediate decision about whether this service is actually useful to you. In fact, what we're seeing in one of our products on the android phone is that people are making decisions not to download an app, based on the information that's provided to them in the sign-on process. The sign-on process has gotten to a point where it's clear enough, in that they've arrived at a piece of information and have said that the usefulness of the app is not valuable enough for them to make that trade-off.
