My philosophy on switching.social is to keep new concepts to a minimum, so that people only have to try one new thing at a time.
If they only have to try one new thing, they are far more likely to try it.
My new concepts are that Fediverse doesn't use ads, so it's less likely to invade privacy, and if an admin does invade privacy you can easily switch to a different instance.
Centralised services are dangerous because you cannot switch without leaving the network.
