Hey, Pinky! I hope you find this engaging. Forums can be a place for everyone, but it’s totally natural to feel overwhelmed.
One of the things I’d personally really recommend is turning your default view to the Categories page if you haven’t already. This lets you go into the individual subcategory views so you can look for what you’re interested in; if there’s no topic, feel free to make one!
In terms of balancing out response, reading, and seriousness, that’s totally up to you. There’s nothing wrong with letting a topic sit or actively deciding to pass on putting your two cents in (and it’s actively good at times – just reading an in-depth and nuanced conversation is a pleasure in itself & weighing in doesn’t always help the situation).
With that said, if you do have a point to make, feel free to drop a thought in. I’d personally lean towards taking things seriously outside of threads with an immediately light air, but that’s just my inclination as a person. Find your own medium and play from there, but avoid making light of other people’s sufferings or passions, as a general rule – it’s rarely a good look.
My only pro-tip for the forum (and my pitch for why it’s worth sticking out with it), you can’t go wrong if you read our Rules & Code of Conduct. We feel that the Code of Conduct, in particular, forms a good barometer for what we expect from users and what we feel makes a fun and enlightening posting environment. If you see folks falling short of those standards, you can feel free to get in touch with the mods about it through the flagging system.
Finally, if all else fails, feel free to reach out to the member of the mod team if you have any questions or want to know about a feature. If you’re curious about is a certain feature, ask on #site-feedback – someone might be able to guide it to you or, all else fails, we’ll look into implementing it if it’s feasible (no promises on this – we’re only volunteers!).
