It is a bug, when scrolling your top posts, you are not supposed to see new posts as well its supposed to be only top posts.
The issue is explaining it to them like that, just tell them the instance that you use or is the most popular one that is not shit, and when they go to the site, they will see the sign up button and they can join and learn from there. After joining an instance you can mostly use lemmy the same way as reddit, I already got my brother and gf to join and they are about as "normie" as it gets.
It definitely would not be a frequent occurrence, just when most people are ready for a bit more, we wouldn't just do it if people where not ready. It will still stay on the old versions but maybe we could work up to like 1.0 or something over who knows how long, It's completely up to the community.
I should also add that the world will still have the cool world gen for the most part as we would keep the same world. And by the time we reach a point where the world gen changes, a large portion of the world will already be beta terrain generation. Like I said it would not be a super common occurrence.
EDIT: I made a poll for this topic https://strawpoll.com/polls/kjn182BrGyQ
A lot longer, I would not recommend doing it with the really large lists. I did it once with a list with over 2500 mods and it took 3 days lol I feel like most peoples time is worth more than that. For the smaller lists like Wildlander is it much more viable. Either way though you will save SO much time compared to following a list manually like Lexy LOTD or Phoenix Flavor.
I am the OP lol, but I think I may have just worded it weirdly. I just meant that no matter what page you are viewing, new posts appear and pushes existing posts down.
