Oh neat - thanks for the info. Those are the kinds of unique ones I’m looking for, especially the 140 character limit one, thanks for the tip! I’ll look for that relay.
Default ones are good enough to get started with. Just keep in mind not to add too much relays (most people try to aim around 10), as they tend to eat a lot of data.
There are some special relays popping up such as wss://purplepag.es - that only stores profile meta data (name, bio etc) - and nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft released a new relay today that only accepts notes that have a max length of 140 characters
