Honestly I'm kind of struggling with the concept. I'm using the connect android app but it's just not clicking for me.. how do I know if I've found the right community? On Reddit there was only one /r/gaming but when i search on lemmy I get lots of small communities all for the same thing across different instances. Am I misunderstanding how this works? This must be how my parents felt when i first tried explaining Reddit to them 5 years ago
