How old are @Hubmum's followers?

# Quick hack to count the age of people replying to @hubmum's survey.
# https://twitter.com/hubmum/status/83935023895556098

# Limitations:
# - It only looks at the last 100 replies to @hubmum
#   (it needs to be able to sift through multiple pages)
# - It doesn't support polish notation (sorry @pubstrat)

# I've got to go to the pub, but maybe another Python hacker can pick up,
# fork this gist, and improve it somewhat? ;-) -- @grahamashton
