Absolutely. I'd trade what we're stuck with today for simple, self-hosted images and links (no trackers, third party scripts, creepiness) in a heartbeat. This is advertising done right.
I guess. But damn, I'm so used to not seeing ads that I spent maybe 10 seconds wondering how the image was relevant to the article. "Maybe UBAR is an Uber side project?", I was thinking. Then I saw "SPONSOR" ;)
