Even Nostr has a Reddit type alternative called Nvote

Nvote

Nvote is a decentralized, vote-driven community similar to services like Reddit and HackerNews. Nvote is powered by Nostr (yes Nostr is more than just posting short or long-form social media text posts).

Why should I want to use this instead of a centralized service like Reddit?

  • It’s lightweight. No ads, no JavaScript. No images except in posts. (inline images can be disabled in settings)
  • Full feature compatibility with privacy browsers like TorBrowser with JavaScript disabled.
  • Community-based spam prevention with no centralized moderators.
  • Publicly available activity data to help the community identify vote manipulation and astroturfing.
  • Anyone can host a Nostr relay and mirror the data.
  • Relays and clients can be run locally or be made public for other people to share.
  • Ability to disable spam filters or even modify the client with custom filters.
  • You don’t have to rely on a single relay for content. You can configure the client to use other relays as data providers.
  • Backend data is owned by nobody and can be digested by alternative clients without the need for special API permissions.

Yes, the service does need some love as it is mostly autoposting from Reddit by the looks of it, but there are a few users commenting I see.
