Meanwhile, your comment violates the site guidelines, first by crossing into personal attack, and second by failing to do this: "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize." And I'm sorry to see that you've been violating the site rules quite a bit, already. We eventually ban accounts that do this, so please read the rules and take the spirit of this site to heart. That means civil, substantive comments only, and no more rants or flamebait.
If huge percentage of the ads you saw on Instagram were pictures of legs with varicose veins advertising some sort of treatment… would you want to see that all the time? Wouldn’t you start to get annoyed and grossed out that they keep shoving that in your face when you’re trying to look at pictures of cats/cars/landscapes/buildings/whatever?
The author doesn’t seem to be complaining the ads exist, they seem to be complaining about the quantity/frequency of that kind of imagery.
Suppose all ads were tagged for their visual content and their ad-hiding functionality looked for categories of content that you frequently hide. That data could be used for better targeting and passed all the way back to creative agencies to influence design decisions.
How is that not relevant to HN?
From that perspective, why would they want to "better" target using proxy metrics for the ones you really care about? Focusing on the CTR[0], why use tags or interests when you can use clickthrough rate itself?
There are so many factors in what causes someone to click; it's a more effective strategy to treat all those factors as a black box, and optimize for the direct behavior you want to encourage.
Added bonus, those black box / supercomplex problems can be efficiently optimized by ML.
[0] CPC is driven by the advertiser side
I'm not here to argue the point so much as let you know that if you don't study the site rules and follow them properly, we will ban you.
And when pointing out that such content is not worthy, as per the site guidelines, people will at best ignore the policy, at worse say you're a sexist.
Maybe the message is that uBlock origin should be installed by default on every browser?
