Whichever responses you get, they are unlikely to be terribly informative due to heavy response bias. Besides, even if you arrived at some reasonable aggregate, you would then have to surmount the pitfalls of ecological inference to be able to draw any meaningful conclusions: it could very well be that users whose preferences influence the most the content of top-voted submissions are far from representative. That is not to say though your guess is ex ante incorrect: programmers almost invariably earn above the median income in every country, especially in the US (and especially in the startup scene); and this is an English-based US site that distinctly up-votes programming and startup content --"niche" topics of very narrow interest to all but a particular sliver of population, and so highly informative in the "Bayesian surprise" sense.
