Mastodon had a moment where a lot of people with large following signed up and tried it initially. They even switched over to create content first on Mastodon.
Yet, the reality was that your following was still on other networks and it was hard to follow and find people in other instances, or even your Twitter followers who are on Mastodon.
You could not just import/export from Twitter to Mastodon. It was like moving to a new city and starting to build your networks from scratch without the depth in niches to make it interesting and rewarding.
I don’t think we can avoid cross-posting. People use different platforms and you want to reach them natively. Creators prefer platforms that bring them the most engagement and the best UX (+ audience).
We could turn it into a positive challenge: how to make it easy so that they post it here first but cross-post it elsewhere? And over time, this platform wins on its own merits, features and opportunities.
The reality is that Nostr is new and strange for everyone in the beginning. After the very early adapters, the rest of the crowd is more demanding and less adventurous. Things should just work out of the box without reading NIPs or beta struggles.
We are not the growth crowd.
