Yes, he has done a really great job with Popular Information.
Still -- a few fine points on this:
- He's covering topics of national interest, which is very different than local when it comes to subscription numbers.
- To that point, "Twitter continues to be the biggest driver of newsletter signups." We've seen that it can be incredibly difficult for local news to trend on social media, namely because -- by definition -- it appeals to a limited audience.
- By being investigative only, it means he can choose what he is willing to cover. Investigative reporting is incredibly important, but it can be very different than replacing local newspapers -- while they can do investigative pieces as well, so much of what they do is covering the events around their coverage area. That takes a team of people, because you cannot be everywhere at once.
- He has a big name. True, he might not have been famous when he started, but the article itself points out that he was able to gain coverage in Wired because what he was doing was such a novelty. Now, the headline of the Substack you linked to doesn't even need to include the name of his newsletter, his own name is so well known.
