advocacy help ( Python vs VB )

[Stefan Kuzminski]

I need to convince my co workers and erstwhile managers to build a
production system in Python.  They're coming from a VB world and are fearful
to detach from the Redmond mothership.  I need hard facts, not warm and
fuzzies about syntax but names of big companies using Python and things VB
just *cannot* do ( threads, regular expressions.. ? ).

Thanks,
Stefan
