Truly. I wonder if ActivityPub could be utilized to create a resilient search engine that shares the cost among federated instances. We already have something like that in Lemmy and Mastodon where federated data can be search from any instance. If the data is pages crawled by some automatic crawler which is then federated across instances which in turn allow to search through it, perhaps it might resemble a search engine. Page ranking beyond text matching could even be done by peoples up/down votes instead of some arbitrary algorithm. Similar to how voting works on StackExchange or Lemmy. 🤔 I'm sure someone is thinking about this.
