cool trick but we all know who will end up using this the most:
advertisers. another way for them to "gauge" their reach and brand appeal. or something.
literally i feel like every new thing that comes to the browser, a marketer at a company thinks, 'how can we exploit this to put more junk into the face of other people?'
i am not against advertising, i just think most of them have no limits in terms of what they'll exploit at the expense of their own users.
