Lack of CS interest in Google trends.

So the other day I was checking out Google trends, and I figured I'd check how my favorite editor, Emacs, was doing.



Turns out that there has been a steady decline in the number of google searches done for "emacs" from 2004 to Jan 2009.
I wanted to see how "eclipse" was doing, but I figured that most of the people that would search for eclipse must mean an actual eclipse, not the IDE. So I then proceeded to see how Java was doing:


As you can see, there is a very similar decline, though with less of a slope.

Intrigued, I checked the trend for the much more general term "Algorithm":


Almost the same decline as "emacs"!! Except for spikes that seem to correlate to school terms.

Now take a look at the trend for "computer science":


If you ask me, I would tell you that this is a sign of a steady decline of interest in computer science/programming, since the very general term "math" doesn't show the same slope:
(Note that there are very marked valleys correlating with school vacations).
