Pinterest had the feature. Users loved it. Then they killed it. Why? It's a classic case of Misaligned Incentives.
Users wanted a utility tool to organize their lives. Advertisers wanted a media channel to broadcast ads. Notes were a 'User Feature' that didn't drive ad revenue.
Pinterest tried to be everything. Social network. Shop. Search engine. In the process, they lost the core simplicity of 'Pinning things to a board.'
Notestopin brings back that simplicity. We don't care about ads. We care about your notes.
