I’m not sure the ‘like email’ thing helps. Email is confusing and not what most people use to connect with others. I don’t know anyone who met via email.
In my experience it at least helps in the sense that, when people ask “why are there more then 1 site?” ? And up to a certain degree you use that to explain the concept of federating.
Oh definitely that the next couple of weeks will be spent preparing for a new wave. I wouldn’t be surprised if that was the reason why Lemmy.ml was down. Yes I know that it was because of a server migration but, that server migration also didn’t happen for no reason ;-)
The first migration wave to Mastodon was very bad. I still remember, that following a person was nearly impossible. Not to mention the fact that, even if you could follow someone, it didn’t automatically meant their messages ended up in your feed.
I know for example that version 0.17.4 of Lemmy (that was released 2 days ago) already has some database optimizations.
