In Notes, writers will be able to post short-form content and share ideas with each other and their readers. Like our Recommendations feature, Notes is designed to drive discovery across Substack. But while Recommendations lets writers promote publications, Notes will give them the ability to recommend almost anything—including posts, quotes, comments, images, and links.

Any migration is likely to face many of the challenges previous platform migrations have faced: content loss, fragmented communities, broken social networks and shifted community norms.

By asking participants about their experiences moving across these platforms – why they left, why they joined and the challenges they faced in doing so – we gained insights into factors that might drive the success and failure of platforms, as well as what negative consequences are likely to occur for a community when it relocates.
