Marketed as a next gen ad-blocker I could see more utility.
On the directly harmful side seems like you could ask it "hide all posts from an opposing viewpoint" to help people create echo chambers.
From a product standpoint, general purpose first-party browser agents (from Microsoft/Google/Apple) might eat your lunch. Though if you get far enough fast enough you might get bought out! ;-)
re: On the echo chamber point — yeah, that’s something we’re thinking about. The intent is to target mechanics (infinite scroll, counters, autoplay), not viewpoints.
re: browser vendors eating our lunch — totally possible. But there’s also an inherent conflict for engagement-driven platforms to aggressively reduce engagement.
Appreciate your thoughts!
