The problem is just when someone in the past said “you should join <forum x>!”, you were always able to just immediately go to forum x’s signup page and sign up. But if someone hears of Lemmy, and goes to join-lemmy.org, there is no way to go to a signup page directly.

People should probably stop saying “join Lemmy”, and instead link directly to the site/instance they suggest

User should create an account on one server

Mostly this. Some people might want a few accounts but those would be hardcore users.

the password/cookie should still work even when awaiting validation, password is set before the email is sent

maybe I’m misreading what you’re saying, but we already have this, works the same way as Reddit

https://join-lemmy.org/docs/users/03-votes-and-ranking.html

the Summit app does it too

Lemmy should have some sort of recommendation alhorithm.

https://quiblr.com/ is a Lemmy frontend that does this

Will Lemmy can become easy like Bluesky? Are there plans like that?

I’m not a Lemmy dev (well I’ve made a couple of small commits lol), but this type of question can be hard to answer from the inside of a project.

It would probably be easier to answer a question more like: “Do you plan to implement feature XYZ in order to be easier to use like Bluesky?”
