It actually downloads as wordpress-2.3.1.tar.gz if you do it with  
Firefox. That's because of the Content-Disposition header sent by the  
web server. Have a look:

In particular, this:

> Content-Disposition: attachment; filename=wordpress-2.3.1.tar.gz

This tells the browser what filename to save the file as, but  
unfortunately wget doesn't support that header, for some reason. I  
guess it makes it easier to predict the filename when running it from  
a script; but I guess if you were scripting it, you'd use the -O  
argument to force it to have a particular filename.
