I’ve seen a demo of Alpha by Wolfram.  It was impressive.  It shows how having specialized knowledge of sophisticated software can enable useful results.

On the other hand, after news today of their “pro” version coming out, I gave it another try.  Simple task: give me a plot of the average high and low temperatures in Denver through the year.  I was looking for climate data.  The NWS site gives it directly, in tabular form, though.  A plot would be nice.  So, I asked Alpha for each, in turn.  You can see that it gave me the same plot for both.  This is quite misleading.  Is it showing the actual temperature for the past year?  Why would the average high and low be the same?  On top of this confusion, there appear to be non-functional crosshairs in the actual site, which one would think would allow clicking in the page to get details.  Not on Safari.
