Hey folks.
Wanted to share this. I've adapted an old fork of the python-oauth2 library to support hitting the Foursquare v2 API.
WARNING: This code comes with the caveat-emptoriest caveat emptor that ever caveat-emptored. It's not pretty, but it does the job. Hopefully someone with more time will make something as cohesive as the v1 API's foursquare.py library.
Rod.
