The tree of life illustrates taxonomy, but really a knowledge graph is needed. Yahoo directory, now mostly forgotten, was the largest online curation project. Awesome lists show us what to do, but they have their limitations. My own experiences taught me what not to do. The required web and email technologies will be reviewed. Integration with ActivityPub will be discussed. In technology there is a business model: curate content to become known as the expert in the field. In political activism, there is a "business" model, curate content to become known as a trusted source of information and in the process attract voters. In other fields only wealthy eccentric hobbyists can do the work. In the future, the government, universities and libraries should be funding curation using federated tools.
