- Temporal Patterns of Happiness and Information in a Global Social Network: Hedonometrics and Twitter (PLOSone) — Tweets involving the ‘fake news’ comedian Stephen Colbert are both happier and of a higher information level than those concerning his senior colleague Jon Stewart.

- Pricing Experiments You Can Learn From — revealing the data from experiments which showed how to drive people towards higher prices.
- 10 Things I Learned at CrowdConf 2011 (Crowdflower) — Using his newly released crowdsourcing platform Coffee & Power, Philip [Rosedale] developed his entire company infrastructure and platform through a globally distributed workforce. 288 contributors in 127 locations worked together to get this startup off the ground in a whole new way. The Coffee & Power platform was built in 1,700 commits ranging from $6 quality checks all the way up to full source-code editing. One element of this process was developing the Hudat iPhone app. In less than a month for $2,485, the Coffee & Power community got this mobile app up and running.
