Just post as usual. See the 'Federated' timeline in one of your tabs/links? That's the outside world (basically, all other instances besides the one you're currently on). People'll see your post in there. Every server that's federating with yours (mas.to in this case) will see your post passing by. Anyone can follow you, no matter what server they're on (provided there's no blocking between servers in place of course).
