The hunt for the next Twitter: all the news about alternative social media platforms

It is fair to say that Substack has had a dramatic week and a half or so, and I talked to their CEO Chris Best about it. The company announced a new feature called Substack Notes, which looks quite a bit like Twitter — Substack authors can post short bits of text to share links and kick off discussions, and people can reply to them, like the posts, the whole thing. Like I said, Twitter.

Twitter, under the direction of Elon Musk, did not like the prospect of this competition, and for several days last week, Twitter was taking aggressive actions against Substack. At one point you couldn’t even like tweets with Substack links in them. At another point, clicking on a Substack link resulted in a warning message about the platform being unsafe. And finally, Twitter redirected all searches for the word Substack to “newsletter.” Musk claimed Substack was somehow downloading the Twitter database to bootstrap Substack Notes, which, well, I’m still not sure what that means, but I at least asked Chris what he thought that meant and whether he was doing it.
