Hi and welcome!
A lot of people who are new to the Fediverse find the initial experience rather sparse, which might turn them off, and that's not entirely unreasonable.
It helps to follow a lot of accounts, but slightly less obvious is that you can follow #HashTags as well. That will populate your feed with any post that uses any of the hash tags you follow, and is a great way to discover people who post about things you care about.
