I would love to see a Mastodon search where I can see who is posting in my geographical neighbourhood or expand to a new people talking about my interest.
In centralized social networks this is most commonly solved by using hashtags and a global search. In Mastodon your searches are limited to the federated content your server knows about.
It is not your server’s task to crawl and index all public content, however, a search engine could try this.
The social network of the future: No ads, no corporate surveillance, ethical design, and decentralization! Own your data with Mastodon!
