I feel they both could be classified as social media. I am hopeful that the slow steady growth and the fact that they are both built with Bitcoin incentives at the core, they will grow in a better way than what we have seen in the past. Nostr grown up will not look like Twitter grown up. And same for stacker vs. reddit. Incentives are important. And the future here won't be just cyber pink types. But there will still be Bitcoin at the middle. Which is exciting. Overall, I think we will age like fine wine here. Only time will tell.
