Good idea!  I propose the following:

comp.lang.python.misc
comp.lang.python.gui
comp.lang.python.networking
comp.lang.python.dev
comp.lang.python.lisp-envy

As the newest Lady Turnpot descended into the kitchen wrapped only in
her celery-green dressing gown, her creamy bosom rising and falling
like a temperamental souffle, her tart mouth pursed in distaste, the
sous-chef whispered to the scullery boy, "I don't know what to make of
her."
