I think I know why I get less number.

I am only looking at the System Context functions. There are other packages 
that come with Mathematica which I am not counting when looking at the 
System context and the blog above must have done that.

Packages such as VectorAnalysis, Quaternions Package, Developer, 
Experimental, JLink, GraphEdit and more which have to be loaded. I suspect 
that the total shown in Wolfram blog must have counted all those functions 
as well. This must have added another 600 functions or so.

If I know exactly the list of packages, I could add them and run the same 
process I did for the System Context to obtain the complete list.

ps. I found the file Usage.m sitting in Mathematica 7 installation folder,

C:\Program Files\Wolfram 
Research\Mathematica\7.0\SystemFiles\Kernel\TextResources\English\Usage.m

which actually contain Usage messages although it seems some of those 
messages are not just for System functions, so I did not use this file.(When 
I parsed it for Functions[], I get different total than with the current 
method I am using).
