“Over 200 million observations contributed by 3.5 million users worldwide.”
Citizen science actually working at scale, which almost never happens. Take a photo of a plant or bug, the platform identifies it and logs the observation, scientists use the data set for real research. No ads, no engagement metrics, no monetization play. Just a quietly enormous public good run by the California Academy of Sciences. The model exists. The rest of the internet just refuses to use it.
