Yes, it's not that easy to find out what is happening with all the relays.

I found this website called NostrNet.Work that it's like a hub of Nostr products. I think it is useful for new users.

Also, what I did my first time in Nostr I followed all relays that nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m and nostr:npub1sn0wdenkukak0d9dfczzeacvhkrgz92ak56egt7vdgzn8pv2wfqqhrjdv9 were following at the time.
