The million-dollar prize for the best article on X is more than a user engagement tactic. It's a clever, inexpensive growth hack to generate a massive corpus of original, long-form content. This data is invaluable for training X's own large language models, like Grok, making the prize a small investment for a significant strategic asset.

A16Z invested in Substack believing that providing writers with a monetization tool would unlock a new supply of high-quality content. This new supply would, in turn, create its own demand, rather than competing in the existing market for free content.

While the internet shifts to video, X's core strength remains its text-based format. This attracts a high-value audience of intellectuals and creators, making it the leading platform for this demographic, according to Elon Musk.

Substack's new policy requiring readers to install its app to finish articles is a major strategic pivot. It moves the company away from its founding ethos of direct, unmediated creator-audience relationships via email and towards building a walled-garden social network, potentially at the expense of its creators.

Medium is no longer competing for professional content creators building media businesses. Instead, its CEO states the platform is focused on being the best place for "real people"—practitioners and individuals—to share valuable life and work lessons without the pressure of becoming a full-time writer.

To attract top freelance talent, Escape Collective is testing a model that can pay more than Substack. They offer writers a base rate plus a share of the subscription revenue directly generated from their articles, aligning incentives and rewarding high-performing content.

X doesn't need writers to abandon platforms like Substack. The high-profile contest incentivizes them to cross-post their best free content to X. This strategy enriches X's platform with high-quality, long-form articles, treating it as a distribution channel that funnels attention back to the writers' primary newsletters.

The media landscape has fundamentally changed. Value is no longer concentrated in institutional brands like the New York Times. Instead, it has shifted to individual, 'non-fungible' writers who can now build their own brands and businesses on platforms like Substack.

Avoid building your primary content presence on platforms like Medium or Quora. These platforms inevitably shift focus from serving users to serving advertisers and their own bottom line, ultimately degrading reach and control for creators. Use them as spokes, but always own your central content hub.
