The guys at BrewAdvice.com, the stackexchange 1.0 version of us, said (way back when we were in commitment phase) that they'd be all for merging with us. They've built up a nice pile of answers, as well as an existing community.
From the sounds of things over there, this is going to happen: https://homebrew.stackexchange.com/questions/1825/meta-are-we-being-merged-into-the-other-stack-exchange-brew-site
Haven't heard anything official outside of brewadvice about this, but it makes sense.
