The problem with Nostr lies in its cost and replication; the traffic is redundant (98% of it). The result is a fragile infrastructure; a "ticking time bomb" in terms of costs. Added to this are the typical headaches associated with any decentralized network (spam, moderation without a central authority, Sybil attacks, a constantly growing volume of data, etc.). Furthermore, it is dependent on relays (which is not the case for other networks).
