@PhuketPaul@mastodon.au try exploring and searching hashtags. Name anything you think you like. Eg. #nature, #auspol, #art. Notice who wrote the posts that interest you and follow them. Look at their bios, #introduction, and timeline, and discover more tags and sometimes a group that you can also follow, like @bookstodon@a.gup.pe or @COVID19@mstdn.social ... and that's how you get started.
