it is scary isn't it? that companies have the power to use our data and tailor their marketing to us? However, there has been so many mixed thoughts about that. Some people believe it is super invasive, others actually prefer having ads that are relevant to them. Each to their own :)

As far as ads go, I don't care, because I don't pay attention to them, but yeah, it's all scary. I can't wait until I have a library with everything I need to know at my disposal and my phone is just a phone. Until then I will take my chances I guess.
