Just in case you didn't already know: the search box at arduino.cc uses the google engine to search the site (including the message boards), which screens out a lot of noise that you'd see search the entire interwebz.
People in the Arduino community have been extraordinarily good about contributing information and experience to the message boards, the Playground, and the rest of arduino.cc. I only do general google searches if I haven't found it here (which isn't often).
