Find the communities that relate to your personal interests. Just like other corners of the Internet, you'll see that there are other people interested in the same thing.
I regularly speak to people on HIVE about my interests: Photography (via the Photography Lovers Community), Art & Artists (via the various Art communities such as Alien Art Hive, On Chain Art, and maaaany others) as well as gaming, via HIVE Gamers.
There's people who tend to take one of two approaches on HIVE.
- Those that are self referential, and just post content about HIVE, on HIVE. My opinion is that this stuff doesn't as much value as the 2nd category.
- Those that want to share their art work, stories, photos, or just general life updates.
