Everyone willing to post their photo, at least. My hardware setup isn't that different than images, but I have 2 laptops KVMed to one monitor and the resulting pile of cables. I have no desire for the world to see my chaos, or my messy office, or my pile of diet mountain dew cans, because somehow admitting to such vices on HN is OK, but documenting them via a photo feels wrong.
You see the same principle behind people's Instagrams. People shoot, re-shoot and meticulously edit their uploads so they're as flawless as possible. I think Reddit has something called 'r/shittybattlestations' as a joke sub to counter the deluge of samey "minimal IKEA desk w/ hyper-expensive equipment" content on the main subs.
