We are making a big mistake in the
#Fediverse when we ask people to sign up for Mastodon.
The end user product is not Mastodon. The end user product is a specific Mastodon instance.
We should ask them to sign up to a specific instance (preferably one that would match their values in the moderation they do, their funding model, their accountability ...)
After all, their relationship is with their server operator, not the open-source project. And lots of bad experiences would be avoided IMHO.
