I think the option of 'curating your own algo on nostr' is a little rogue atm. Here’s a tip tho - head over to nostr.band and key in any word that interest you. A bunch or people and conversations around it will be listed out - add them to your follow list. Rinse and repeat - And your timeline will be more curated by you, for you. advance search like dvms are still wip, but nostr.band is steady. Good luck with the talk! You’re gonna do great!
