I would agree with this on the whole. And also that it is generally better to 
add modules to your system python via the distro's repo because that bring 
benefit to every user on the system, not just yourself.

I'm directly advocating _not_ adding PyPI packages to the system interpreter.  
If nothing else, they may differ in behaviour and potentially actually break 
system behaviour.

Having your on virtualenv is good for: adding packages no provided by your 
vendor, adding packages deliberately different from those from your vendor (eg 
newer versions with specific bugfixes or extra features), having an isolated 
environment for packages (you can make more than one virtual environment).

And of course it avoids interfering with your system python install.
