To Twitter migrants complaining about learning how to use the Fediverse—do you forget what it was like to first join Twitter?

Questions that arose back in 2008:

1. What can I possibly say in 140 characters?
2. What is a hashtag, and why does it even exist?
3. How does anyone find anything?
4. Who do I follow?
5. What's a feed?

Twitter came with a learning curve.
