This is a most excellent place for technology news and articles.
And targetted ads aren't that much more effective than context based. So the internet has been compromised, misinformation has run rife, and platforms hijacked to threaten democratic nations so some corporations can have 6% more effective advertising. What a deal. I believe thats the approx effectiveness difference.
