If you have to choose a relay to pay definitely look for nostr.wine

It is probably the best relay actually and it also has the additional filter/broadcast relay with it.

Once you have that, your journey on #Nostr will depends a lot based on what client are you using.

I suggest to try these:

Amethyst

Damus

Snort

Nostrgram

Iris

Everyone of them has its own features and the usability and the feed will look slightly different in any of them.

Another suggestion is, to follow people your favourites user follow. In #Nostr you, me, everyone is the Algo.
