I did give mastodon a go, but I found it confusing, when I make account is that for that specific instance? If I choose one instance, can I see things from a different instance?
>> When you first create your account, you choose a server — similar to how you choose to open an email account on Gmail, Hotmail, Yahoo or wherever — which generates your profile’s address. So, for example, if you sign up for Mastodon via the climate justice server, then your address will be @[your username]@climatejustice.social. But no matter which server you sign up with, you will be able to communicate with users from any other server, just like how Gmail users email Hotmail users and vice versa. However, some servers might have blocked other servers (perhaps if it’s an unsavory group), which would mean you can’t communicate with anyone from the blocked server.
Microsoft is the only company that i know of with a true EEE approach eg with Java
