<p>I love these incredibly simple and elegant classic technologies. GPS is one of the best. It seems like it would be incredibly complicated and mysterious, but it's actually quite straightforward.<p>I'm working on a presentation now to explain how GPS works to second graders. If they understand it, I'll take some photos and do a write-up.</p>

<p>I think you have identified the crux of my objection to this piece. The OP is mostly talking about cases where a truth about someone is so much more widely known than other truths about them that it becomes overwhelming in perception of that person.<p>The problem to be solved here is not the liability owed by the reporter of the truth, but rather the way in which our reptilian brains fail to balance that truth against an undoubtedly bigger picture.</p>

<p>This (ironically). I often start enforcing a "no pronouns" rule for myself and others when conversations and concepts get more complicated. It (the rule) is awkward at first but makes a big difference in mutual understanding.</p>

<p>Counterpoint: a friend in Brooklyn was mugged for only around $10 but almost immediately after ran into street police on patrol. They jumped in the car with him and summoned other local cars to catch the robbers successfully.<p>The police want to catch the bad guys too, but after 8 hrs has passed, it becomes virtually impossible to succeed.</p>

<p>Fair point. If you prohibit everyone, including walled gardens, from targeting based on user behavior or user data, that seems like a plausible solution.<p>It's a purely regulatory solution, though, not technical as the top level comment suggested :)</p>

<p>Tracking definitely works, at least in my experience. That's why Google and Facebook have completely taken over the entire digital ad ecosystem. They just have much better data, and your spend is an order of magnitude more effective than buying directly from publishers.<p>Take the camping example. If I sell camping equipment, I can try to reach out to blogs directly, but I will have to place hundreds of campaigns for $100 each, track and monitor them all separately, and count on each of the blogs to deliver them accurately in good positions with no fraud. Or I can just buy one massive campaign with Facebook that runs across Facebook and Instagram and targets people who are interested in camping and maybe even expressed purchase intent. That's the better option every time. The transactions costs of dealing with individual websites are prohibitive.<p>Google (and the other tracking companies) just distribute that same option across the open web. If you get rid of it, Facebook wins absolutely.<p>I like the idea, as one commenter expressed, that the open web would be better without advertising. But I think the reality of an infinitely powerful Facebook is that the open web would be a wasteland and afterthought.</p>

<p>One potentially negative unintended consequence: closed systems like Facebook become even more powerful than they already are. Their revenues will dwarf (even more than they do now) any other free digital platform that can't re-create a fully targeted ad product entirely in-house.<p>Without Google AdX and the mess of disturbing cross-site tracking, I can't see why advertisers wouldn't just spend 100% of their digital budgets in walled gardens. It would just be <i>so</i> much more effective.</p>

<p>I like the Hemingway app, but it is very much designed to make you write like Hemingway (ie short, clear sentences _only_). Obviously most great writing is not in this style.<p>The Hemingway app is good for work emails and marketing copy, or if you happen to like that style. It is hardly the universal arbiter of "poor or confusing writing".</p>

<p>There's a somewhat pervasive idea that advertising and brand recognition are coercive tools that will ultimately die out, replaced by better objective information about products. I'm kind of partial to this idea myself.<p>But increasingly we seem a long way from achieving this. Amazon reviews have become such garbage, I've fallen back to pretty much relying on name brands as my placeholder for product quality.<p>There's still a lot to be said for established brands. Brands can afford widespread advertising because they have thriving businesses that generate lots of cash. Brands can get stocked in major retailers because you need decent products to make it through Walmart's buying process.<p>These are signals that are harder to fake, and they're kind of the best we've got right now.</p>
