Although I agree that "hacker" has a new meaning (and has for a long time), much like how the LGBT community adopts otherwise derogatory terms, I don't think we should stop using "hacker" because of outside influences; the actual meaning implied (coder or script kiddie) is often obvious thanks to the context it gets used in (CNN using "hacker" in a news title is different to when Joel Spolsky uses it, for example).
