As in physics the nature and limitations of any measuring tool and concept is part of your research. Personal use of the Alexa toolbar affects measurements only when what one, or a few, persons do matters in the statistics.
That's not really true - apart from the statistical error, there are also systematic errors, and those remain when a single person is insignificant enough not to influence the statistics. For example, it used to be (I haven't checked recently) that Korean files came out relatively high in the Alexa rankings - presumably because the Alexa toolbar usage was high in Korea.
