I think programmers are always very trendy concerning new services. Think about how reddit was mostly programmers/startups at first or how facebook evolved from being a very specific audience. It'll take some time but in a few years everyone will be as quick as programmers to "google it". And when that happens, the other stackoverflow will certainly get a big bump.

Also, I think for some stackoverflow, it's not enough to tweak the colors.. Some of them might need a real disruptive tool to make it happen. For instance, the cooking one could have a hardware adapters to be used in the kitchen. Ok, that was a silly example, but I hope you get the idea.
