@Helene I'll answer this one here. ^_^
> That illustrate my main feeling on Mastodon : so many instances, I'm missing so much from all those places I will never see. And I don't have time to duplicate myself like you do, it's already too much with T2-Bluesky-Mastodon 😬
It's a good question.
At first, it appears that one is missing a lot because there are different instances or servers. However, if we consider it from the #Facebook + #Twitter + #Instagram + #Tumblr + #Goodreads + #Twitch + #YouTube + #Blogspot era/setup, it is actually the same thing.
1. Even on these non-federated platforms, for example Twitter / #X, you actually miss a lot too. Or from Facebook, you actually see only those that Facebook's algorithms want you to see (you don't even see everything from your 1st Level connections [i.e. those you added as friends and those you chose to follow are also filtered by their algorithm]).
2. If you want to follow someone using Instagram but doesn't have a presence on Twitter, you will be forced to create an Instagram account.
Or, they have a Twitter account, but they are not updating it because they chose to make Instagram their main #SNS presence.

This is where the #Fediverse has an advantage: you don't have to create a #Pixelfed account to follow someone who prefers to share images and photos.
Or if you want to follow a #WordPress blog, you don't have to create a #WordPressDotCom account, if they added the #ActivityPub / Fediverse add-on, you can follow them from your own fediverse account.
In the old way, you have to create an account for each platform. However, in the Fediverse way, you don't have to.

I have a Pixelfed and #BookWyrm account, to mention a few, for my images and #bookshelves needs. If you like to follow images I upload and/or books I've read, you can follow me at @youronlyone@pixelfed.social and @youronlyone@bookwyrm.social using your existing @Helene fediverse account.
You don't have to create accounts there, like how you would for Instagram and Goodreads.
People like me, who have multiple accounts in the fediverse network, are advance users and who have specific needs and reasons.
It is like having multiple emails: I have a separate email per service/platform. I have a separate email per games.
