There are quite a few potential replacements for Reddit, but of all the projects I've seen so far, nostr checks the most boxes:
1.) They got identity right. In nostr, your identity is a key pair, which is not bound to a server like in the fediverse (e.g. Mastodon, Lemmy).
2.) They got decentralization right. Everything in nostr is a signed message, published to one or more relays. Since relays don't do anything more but store and forward signed messages, they can easily be replaced without losing your identity or data. Also, no blocking drama ("fediblock").
3.) They got extensibility right. Since signed messages are the only building block, and clients are only views over messages, new functionality can be added unilaterally. Just write a new client, and everyone can use it instantly with the existing identity and data - zapddit is a good example.
What's missing yet are moderated groups and an algorithm to sort your feed. But this can (and probably will) be implemented at any time by anyone, and there can (and probably will) be competing implementations, which is a big plus IMHO.
