Two obvious monetizing ideas that would be more or less community compatible:

1) you sign up for reddit gold, you get https access to the "nice" servers that have very low load, low latency, tons of BW, cached (fast) image links ... Non-donators get "the best effort swamp" which doesn't work any worse than it does now, but who doesn't want a faster UI?

2) data mining. Hey "big rich corporation" for only $1000 (a month?) I'll send you a detailed monthly report of what "the internet" REALLY says about you, or your industry segment, or the world in general. Presumably your PR people will be fascinated. You could hire a couple interns to slowly search via the UI and/or google but we have the raw DB data ready to automatically mine and we can summarize it for you far cheaper and more effectively than you could by yourself.
