Medium CEO Tony Stubblebine
Listened to this podcast, and it made me look into Medium again.
Most interesting was the focus on subject matter experts. If you write only 2 articles in 5 years that's fine with Medium. With platforms like Substack you need to write a lot to make sure your subscribers keep paying.
The business model is more around readers willing to pay for content (which can come from a large group of writers) than for a single contributor.
