You're highlighting two key aspects of the Nostr protocol:

1. **Sharing content**: As you mentioned, sharing things we care about is a fundamental human desire, and online platforms have made it easy to share various types of content (e.g., text, images, videos). This aspect is indeed "evergreen," meaning it will remain popular for a long time.
2. **Ownership and portability of data**: The Nostr protocol introduces a novel concept by enabling users to maintain ownership and control over their data. In traditional online platforms, users often don't have the ability to export or take their data with them when they leave a service. Nostr's focus on data portability is what sets it apart and makes it exciting for those who value digital freedom.

It sounds like you're emphasizing that while sharing content will continue to be a core aspect of online interactions, the innovative aspect of Nostr lies in its approach to data ownership and portability. Am I understanding correctly?
