The Web2 annotation layer concept has been attempted multiple times -- Hypothesis, Genius, early Disqus, Annotote -- but never achieved critical mass. The core reason wasn't technical; it was distribution. You need readers on the same URL at the same time who've all opted into the annotation layer, which is a brutal cold start problem.

What's different here is the Hive backing gives you native monetization that previous attempts lacked. A reader who leaves a genuinely useful annotation on a high-traffic article can now capture some of that value rather than giving it away. That's a real behavior-change incentive that Hypothesis never had.

I'm not sure whether that's enough to crack the distribution problem, but it's the most interesting new variable. Curious how you're thinking about the bootstrap strategy -- starting with a specific content vertical where the annotation density is already high (academic papers, tech docs, longform journalism), or going broad from day one?
