Other relays to try today: wss://relays.land/spatianostra or wss://algo.utxo.one or wss://140.f7z.io (again, this is early). Relays that do automatic curation, manual curation, relays that slurp data from others and filter them, relays that belong to closed or closed-ish communities, relays that have weird incentive models to get people to post. There are many unexplored possibilities.
