WefWef currently seems to be one of the most-commonly recommended apps for new users. For a lot of the refugees currently migrating from the Reddit 3rd party apps that got shutdown yesterday, this will be their first experience of Lemmy/The Fediverse.
As such, I think it'd be a really great idea to have a little new user experience that explains some basic concepts e.g
Basic app usage
What is Lemmy?
What is an instance?
Does it matter what instance I pick?
How do you create an account?
Discovering/Subscribing to communities
We don't want to scare off by being too complex so presentation is everything. The key thing is giving people just enough info to help them get set up with an account and subscribed to some interesting communities (and ideally with a very basic understanding of instances)
