I think even in the days when Alexa was thought of as important, the data was very inaccurate and easily manipulated. The Alexa bar was generaly only installed by people within our industry. It was a figure based on the demographic of the user and often altered radicaly by the site owner.
IMO it has no value, and never had any meaningful value.
