Not sure I agree there. There are lots of interesting posts which sink on that queue and fall off it without getting sufficient votes to be seen, while less interesting but more controversial stuff floats to the top. All it would take is a few score more people voting technical stories up consistently to change the story mix.
Who says there aren't already? Note that what's on the front page is just up-voted content. Tons of stuff (some quite good) slips through the cracks every day.
