Very thoughtful analysis. I particularly like the insight around the industry metrics and Goodhart's Law. “DAU” and the like align with social media companies’ interests of increasing attention and time on site, which lead to more ad revenue. But, they are at odds with their users’ interests, or at least don’t consider user costs (ie time). I wonder if a social product could thrive based on the principle of “efficient” usage, a la the platform works on my behalf to keep me efficiently informed on what’s going on in my network and considers the cost tradeoffs of my time and attention. I suspect I could feel very “up to date” on the things I care about most by checking into a social product ~weekly with a thoughtfully curated digest of content.
