Well, I think this gets back to our privacy philosophy. We think it's really important that it be clear with users why we're collecting the information and how it gets used, and that we give them abilities to delete the information and to do so in a way that's more granular than just deleting your account. We try to do things that are a little more fine-tuned, such as how you can delete the location from your tweet without actually deleting the tweet itself.
That's where we think that if you give users options like that, it helps them make informed decisions, and they're then empowered to protect themselves.
