If Reddit serves 20 billion page views per month, at an average of 5MB per page (these numbers are at least in the vicinity of being right), then reducing the page size by 10% would by your maths be worth 238,000 burgers, or a 50% reduction worth almost 1.2million burgers per month. That's hardly insignificant for a single (admittedly, very popular) website! (In addition to what justmarc said about accounting for the whole network. Plus I suspect between feeding them and the indirect effects of their contribution to climate change, I suspect you're being generous about the cost of a burger.)
