Probably a very polarizing question.
On the one hand, having most of the users and communities on LW causes technical issues (see this post), and also gives the LW staff too much power over Lemmy as a whole.
On the other hand, with 18k MAU on LW out of 47k (https://fedidb.org/software/lemmy/), every community listed there has a much higher chance of visibility compared to an alternative hosted on another instance
I guess I’m your person this week. I thought you had to create a new account to switch instances. The only time I’ve moved so far was from kbin.social to lemm.ee so I definitely had to but it’s nice to know that if I want to move again I can keep the same account.
To be completely correct you will have to create a new account, but you can export and import your subscriptions and block lists from the new account to the new one in a few clicks
