New people don’t get much engagement because established users don’t follow new people so they leave. They feel like they are talking into the void (because they do). Even commenting on notes doesn’t get you that many followers.

This is why it’s so critical for Nostr to grow or it may very well die. Without new people, the number of users will shrink over time. You need relatively new folks to engage with other relatively new folks because they’re more likely to follow each other and stick around.
