Reminds me of <a href="https://toppub.xyz/" rel="nofollow">https://toppub.xyz/</a><p>I wonder if this makes sense, given Substack's model. Other leaderboard-style projects, like Top Pub, make a degree of sense because of the nature of their community. Medium publications, for example, rely on contributors and, often times, sponsors/advertisers. Both these groups are incentivized to work with the most popular publications, and so publications are incentivized to publicize their stats on leaderboards. With Substack, monetization is built in to the platform, and a given newsletter typically has a single author (i.e. no need to attract armies of contributors).<p>I'm not sure what incentive a publisher has to work with a leaderboard in this scenario—but I'd love to hear what it might be, as I'm by no means an expert on the Substack ecosystem.
