Niche Community Newsletter Curator

A weekly or periodic newsletter service that curates the best content, discussions, and updates from a specific community (like Obsidian users). Saves community members time by aggregating scattered information into one digestible digest.

Newsletter fatigue is real, but hyper-niche digests focused on single tools or communities (like the existing Obsidian Roundup, which ran successfully for years) consistently outperform broad aggregators because the audience self-selects and churn is low. The closest incumbent model is Substack, which is a distribution layer rather than a competitor, meaning no one owns the curation layer for most niche communities. The $200–1.5k/mo revenue band is honest — sponsorships from tool vendors or affiliate deals make sense at small scale, but growth beyond that ceiling requires either audience size that takes years to build or charging for access, which niche free-content audiences resist. The real kill condition is that this is a person, not a product — it's a writing job with light tooling, and the moment the curator burns out or loses interest, the whole thing collapses with no defensible asset left behind.
