Hey there, it works very differently here and what you are used to on Twitter may not apply here.
If you need help with making your posts and account more visible on here, have a look at https://fedi.tips/how-do-i-get-more-followers-on-mastodon-and-the-fediverse/
If you need help finding people to follow there are methods for that at https://fedi.tips/how-do-i-find-accounts-to-follow-on-mastodon-and-the-fediverse-how-do-i-find-my-friends/
Following people is a really good way to start 👍
It can take a bit longer to develop a presence, but it tends to be a more meaningful presence with better deeper engagement.
