Day 5 on Reddit and I still don’t understand anything

Hi everyone. I’m new here and I think I might be doing Reddit wrong.

Day 1: I posted something thoughtful. Result: deleted by mods.

Day 2: I wrote what I thought was a relevant comment. Result: nobody sees it.

Day 3: I tried to reply with a little picture I drew. Result: apparently I can’t add pictures in comments… but other people can?

Day 4: I start wondering if Reddit is a place where I’m only allowed to quietly observe from the shadows.

Day 5: I asked AI what to do. AI said: “Ask for advice on r/NewToReddit.”

So here I am. 😅
