A variation on last year's Dear Santa, a chapter crowdsourced from each US state, populated from a Twitter search.
Get Twitter app keys and secrets and put them in whatis.yaml:
consumer_key: TODO_ENTER_YOURS
consumer_secret: TODO_ENTER_YOURS
access_token: TODO_ENTER_YOURS
access_token_secret: TODO_ENTER_YOURS
Then run:
pip install pyyaml twitter
# then for tweets from the 50 states
python whatis.py > whatis.md
# or for tweets from anywhere
python whatis.py --no-states > whatis.html
Works at least with macOS High Sierra with Python 3.6.3 and Python 2.7.14, and Windows 7 with Python 2.7.11.
