      Here's a summary of the online usability study of two Apollo Program
      websites which many people in this group participated in:

      An online usability study of two websites about the Apollo Space Program
      (NASA and Wikipedia) was conducted as an illustration of the technique. Each
      participant attempted four tasks from a full set of nine using one of the sites.
      A total of 130 people completed the study. Task completion status and task
      time were automatically recorded, as were responses to a variety of post-study
      rating scales and open-ended questions, including the System Usability Scale
      (SUS). All performance metrics (task completion, task time, task efficiency)
      showed that the participants performed significantly better using the
      Wikipedia site. Similarly, all but one of the self-reported metrics showed that the
      Wikipedia site was perceived as being significantly easier to use. The one
      exception was that the NASA site was rated as marginally more visually
      appealing. Extensive comments on both sites are consistent with these findings and
      give additional insight into aspects of the sites that could be improved.

      Congratulations to Susan M., who was the winner of the random drawing for
      the $20 Amazon gift certificate! Many thanks to everyone who participated in
      the study and the discussion about it.

        Very interesting, Tom. 

        I  wonder how much of the results can be attributed to the participants likely having prior experience with Wikipedia.   Your thoughts?
