It is possible, as oil from the skin works its way into the surface of the key. Cleaning the keyboard can help prevent it.
My keyboard is still relatively new, so, no. I use clorox wipes to clean the keyboard and trackpad about once a month - while the machine is off.
Happens on any laptop. Ever seen someone with a really old laptop that has the letters coming off or it has noticeable splotches/circle marks? Yeah that's years and years of finger oil that seeped into the keyboard. Even my current gaming Asus that I've used for for 2 years is starting to get those spots.

Never considered that, just usually keeping it dusted and dust free. I'll start making it a point to do that once a month.

On my Air the keys have started to go a little bit shiny on the keys I use the most and I don't really clean the keyboard properly all that often. It's mostly the wear I think and the oils seeping in, apart from looking a bit odd it doesn't really damage the overall aesthetic or functionality of the keys so I don't mind.
RadTech OmniCleanz. It's non-conductible so it won't harm electronics. It removes oil and other dirt without leaving a residue. It's great for displays, camera lenses... you name it.
I recently sold a 3.5 year old MBP for top-dollar in part because it was in mint condition. Regular cleaning using OmniCleanz kept it looking like new.
