Why is there no mention of Gears or settings in this subsection?

I was curious why this subreddit isn't like other photography communities where people usually mention their gear and settings when posting an image. I find it a bit odd that no one does this isn't it sort of an unspoken rule in the photography community? Specifically to help others? 1 word when you ask about the gear people answer like Sony 6700 and that's it why?
