Meedan (from the Arabic for town square or gathering place) is a global cabal of journalists and technologists working on open source software designed to _deepen_ (context, annotation, fact-check, verify) and _widen_ (translation) the www. Check is a platform for collaborative fact-checking and verification. It powered more than 1000 journalists working on Electionland, the 2016 US Presidential Election monitoring project led by ProPublica which has been called the largest single day collaborative journalism effort in history. Bridge is a platform for social media translation which is currently being re-written to meet cross-language communications needs of aid workers and affected populations in crisis.

Meedan is leading the Knight Prototype winning Credibility Indicators Working Group which is an effort to develop a set of human and machine readable signals for disputed content, claims, and sources.

Talk to me about the impossibility of quantifying the truth and the strange magnetic pull of windmills.
