I’m on kbin too. If you’re ever wondering where someone is commenting from, you can tap their username and their profile will show the instance name. If you’re ever wondering what platform the comments are hosted on, the sidebar (where it says magazine) is the easiest way to see that. I pay attention to that because I know some instances have different moderation rules - for example, Beehaw (which uses Lemmy) is a community that tries to create a safe and productive discussion environment, so I try to be mindful of my actions there to help make sure I’m not interfering when I visit. :) I like to think of it like traveling from my home country to other countries. Norms and customs might different, but we all have some commonalities in how we’re built and communicate at the end of the day.

Lemmy and kbin are just different types of software for communicating, kind of like how you can use an Outlook account or a Gmail account for email. They use the same protocols, but have different interfaces and features. Personally, I like kbin. But either is just fine. Technically, you could even use Mastodon to read this, though that would kind of be like using a terminal for email. It’s possible (I’m sure), it’s just not fine tuned for this type of content or use case.

You’ll get the hang of it quickly. Welcome, be nice, and have fun!
