My approach to nostr is a little bit more guarded with my new npub (not this one). I'm trying to route everything with my vanity npub/nsec, through my local relay.
It is not clear to me how that propagates out to the larger network, however, and I'm fearful of exposing my nsec to other relays at this point.
Perhaps my understanding of paid relays is lacking at present, but I'm seeing the rush to using paid relays as possibly incredibly short-sighted, given we're trading off one set of centrality issues for another...
