Substack, the subscription network platform on which you can pay to follow writers, recently launched Substack Notes: a social media feed that aims to "convert casual readers into paying subscribers" by making interesting newsletters easier to recommend.
Substack Notes garnered some unexpected attention when Elon Musk had Twitter mark Substack links as unsafe and suppress Substack search results while accusing the company of stealing data from his site for their "Twitter clone." He eventually reversed this policy but unintentionally gave Substack Notes more attention than it might have received otherwise.
