Hmm. Looks like Twitter API authentication isn't working for the Python twitter library. I assume this means Twitter has finally shut down its open API? Don't have time to investigate this until the weekend. For now, NavierStokes won't be bridging messages between Twitter and other open social media services. Could be a fluke ... but given the behavior of leadership at Twitter, I am erring more on the side of this being some new money-making bulls**t.
